Wow. "Worst attack on Judaism since the Holocaust". Oh yes, of course, circumcision is the essence of Judaism. Not the covenants with Abraham, Jacob and Moses are; no, circumcision is the essence.

Now turned to 11.
Seriously, they are completely out of touch with reality. Oh, and
here's another one, directly from the horse's mouth.
I'm so going to pick that op-ed apart!
Their arguments are plain stupid. Seems they simply did not think it through, or are unable to do so, if they want to justify it with stuff like "uh, well, its an old religious tradition!". I'd love to hear if they are OK if i would go around, cutting hearts out of live humans, and then tell them "duh, that's just an old religious tradition from the aztecs, and i happen to follow their religion!".
Cut out hearts? Blood libel!
What i really find troublesome is their constant harping about antisemitism. Don't they recognize that the more often and quicker they pull out the antisemitism-weapon, it will quickly become a really blunt weapon? And comparing the courts ruling against circumcision with the holocaust? Really? Are they that stupid?
The word antisemitism has already lost its meaning, precisely for the reason you mention. I don't know how many times I've been called an antisemite when posting a critical comment about Israeli policy on the Haaretz site (and that's a liberal paper); or even here.
Okay, now the op-ed of the Chief Rabbi of GB.
It is hard to think of a more appalling decision. Did the court know that circumcision is the most ancient ritual in the history of Judaism, dating back almost four thousand years to the days of Abraham?
Don't lie, Rabbi. Abraham was a mythical figure, and you have no proof whatsoever that circumcision goes back so far. Judaism doesn't even go back so far: as a monotheistic religion not before the Babylonian captivity, and as a henotheistic Yahweh-cult to maybe 800BC.
Did it know that Spinoza, not religious but together with John Locke the father of European liberalism, wrote that brit milah in and of itself had the power to sustain Jewish identity through the centuries?
Maybe you should have first thought of preserving Spinoza's Jewish identity? He's the only case I'm aware of that has been excommunicated by the Amsterdam Jewish community.

But this reference is the ultimate chutzpah. What Spinoza actually wrote in Chapter 3 of his
Tractatus Theologico-Philosophicus was all but flattering about circumcision. Here is what Spinoza wrote, with some context:
Spinoza said:
(98) At the present time, therefore, there is absolutely nothing which the Jews can arrogate to themselves beyond other people.
(99) As to their continuance so long after dispersion and the loss of empire, there is nothing marvellous in it, for they so separated themselves from every other nation as to draw down upon themselves universal hate, not only by their outward rites, rites conflicting with those of other nations, but also by the sign of circumcision which they most scrupulously observe.
(100) That they have been preserved in great measure by Gentile hatred, experience demonstrates.
<snip>
(104) The sign of circumcision is, as I think, so important, that I could persuade myself that it alone would preserve the nation for ever. (105) Nay, I would go so far as to believe that if the foundations of their religion have not emasculated their minds they may even, if occasion offers, so changeable are human affairs, raise up their empire afresh, and that God may a second time elect them.
Having read that, do you really think Spinoza thought circumcision was worth preserving?
Did it know that banning milah was the route chosen by two of the worst enemies the Jewish people ever had, the Seleucid ruler Antiochus IV and the Roman emperor Hadrian, both of whom set out to extinguish not only Jews but also Judaism?
Please tell the whole story. Hadrian wasn't exactly pleased with the Bar Kochba revolt, that tied up more than 6 legions. He didn't set out to extinguish the Jews, only to crush the revolt and restore order.
If it did, then there are judges in Germany quite willing to say to religious Jews, in effect, “If you don’t like it, leave.” Do judges in Cologne today really not know what happened the last time Germany went down that road?
There are Reform Jews who don't circumcise; in the 19th Century that was even common in Reform circles. Was Theodor Herzl no religious Jew for not having his son circumcised? Ultimately, there's a way around any religious precept.
The case – like the banning of shechitah by the Dutch parliament, now thankfully reversed – illustrates the deep difficulty Jews are facing in Europe today. Both cases initially had nothing to do with Jews. They were directed predominantly against Muslims, whose population vastly outnumbers that of Jews in almost every country in Europe.
Again, don't lie. Neither the Cologne court, nor the Dutch legislative initiative by the Animal Rights Party, was directed against any one religion in particular. It was directed at a practice which today is considered barbaric, irrespective of who does it. Both cases just happened to be a problem for the same two religions that uphold those same outdated practices.
It follows that any assault on Jewish life – on Jews or Judaism or the Jewish state – must be cast in the language of human rights. Hence the by-now routine accusation that Israel has committed the five cardinal sins against human rights: racism, apartheid, ethnic cleansing, attempted genocide and crimes against humanity. This is not because the people making these accusations seriously believe them – some do, some don’t. It is because this is the only form in which an assault on Jews can be stated today.
There's the old canard again: criticism of Israel == antisemitism. It's verboten to criticize Israel because the Holocaust. Phuulease. This is not an I/P thread, so I won't go into the details, but please read, say, Benny Morris on the ethnic cleansing claim.
That is what the court in Cologne has done. It has declared that circumcision is an assault on the rights of the child since it is performed without his consent. It ignored the fact that if this is true, teaching children to speak German, sending them to school and vaccinating them against illness are all assaults against the rights of the child since they are done without consent. The court’s judgement was tendentious, foolish and has set a dangerous precedent.
That's a mighty collection of strawmen, Rabbi! It would be a breach of human rights
not to teach your children a language; education prepares them for adult life, and vaccinating protects them against deadly illnesses.
Circumcision has none of those redeeming qualities. The only quality you highlight, Rabbi, is that you brand your children with a mark saying "I'm a Jew". You could as well tattoo a number on their arm. Of course, that reminds too much of Auschwitz; but then, Rabbi, you forget how many men ended up in Auschwitz because their trousers got pulled down and they were thus outed as a Jew. If you're so worried about a repetition of the Holocaust, dear Rabbi, maybe you should consider stopping branding your folk with a sign that says "I'm a Jew". Under the line, that is your only argument: you want to brand your children with a sign saying they're Jewish. When Jews assimilate and take on more and more practices of the surrounding world, that sign in their pants is the last thing that says they're Jewish, as Spinoza argued, and is your last hold to distinguish your folk from the others. In the end, your holding on to this practice is a sign of your ghetto mentality.
And when about everyone you come in contact with thinks that circumcision is barbaric: Greek philosophers who thought Judaic monotheism was attractive, Romans like Emperor Hadrian, Christians from Paul of Tarsus who argued you could uphold the Law without circumcising, onwards; and modern-day human rights advocates, and many others; maybe then, Rabbi, you should really think about it whether that practice simply is barbaric, and whether you should not abolish it. You can do that, there's a smart exegesis of every law. And after all, the Israelites who dwelt in the desert during Exodus weren't circumcised either.
