Nobody is denying you the right to sceptical inquiry into Islam.
But if a poster exceeds his or her quota of Islam-related threads, then it seems their sceptical inquiry becomes a right ripe for denial, on account of suspicion of "Islamophobia."
The right-wing tax thing you found is interesting. It may be helpful to remember, though, that the American tax exemption for churches is contingent upon the beneficiary refraining from political activity. As you can imagine, there are frequent disagreements about compliance with this provision, since some denominations, not only Islamic groups, might discuss during services how to vote on gay marriage or abortion rights ballot measures, or to contact representatives about pending legislation of various kinds, or to support this candidate for office rather than that one.
So, while the particular source you dug up is without doubt a mouthpiece for all sorts of disputable assertions, the principle that is mentioned actually exists, and is a real feature of tax code enforcement in the United States. The real-world concern is not peculiar to Islam, even if its florid expression is, in your source.

Bigotry does indeed exist. The question before us is who pracitces bigotry, and who, after making sceptical inquiry finds something troubling in one religion which distinguishes it from some other religions. Rationality can do that, "one of these things is not like the others" happens.
"Lableing an entire religion as a 'special threat to civil society,'" is curious. Whom are you quoting? Dr Harris said
... the specific tenets of the faith pose a special threat to civil society...
There's nothing there about any "entire religion." Dr Harris does not plausibly find abstaining from pork a threat to civil society. He plausibly finds vegetarianism, which is a feature of some religions, unthreatening. So, he must be talking about some specific tenets, not all of them.
That Dr Harris did not comment on the diversity within the religion does not imply that he ignores it. If there is a disagreement about what the tenets are, then that's all very interesting, but Dr Harris was commenting on the tenets as he understands them. This is no different than if one of us comments on Xenu beliefs in the context of Scientology. Many Scientologists don't believe in Xenu (many haven't paid the fee to learn that there is a Xenu). It does not follow that I cannot speak about that aspect of the religion, or that if I do so without interrupting myself to acknowledge the many and varied potential sources of Xenu-denial, then I am a bigot.
Dr Harris also did not comment on how many people are ever dishonest about what they and their co-religionists believe, nor did he say that all disagreement with him about tenets stems from dishonesty. The parallels with Scientology are obvious: some person might claim "Scientologists don't believe in Xenu" because they haven't paid enough yet (and so, disagree honestly), while another says the same thing, knowing about Xenu, but also knowing that to acknowledge the teaching would expose their faith to ridicule (and so, disagree dishonestly). I am entitled to denounce the latter, and may do so without elaborating on the former.
So, while there may be no doubt that a certain pattern of behavior would be bigortry, there is some doubt that Dr Harris would be an apt person to ask to comment about that behavior. Of course, maybe you didn't mean to insinuate anything about Dr Harris' character. That'd be good, then there'd be no need to defend him for speaking his mind with integrity and goodwill, as, to all appearances, he did on this occasion.
