Except that's not true. Reading the quotes it seems to me that the only one which makes a broad statement is the PZ quote. Every single one of the others addresses an individual or defined group of some size which does not include "everyone who disagrees with them".
In this post, the guy seems to define the points atheism plus in rather broad terms; he says they're against sexism, racism, and homophobia or whatnot; and he seems to absolve anyone who is against those things, not only those people who are members or agree with everything atheist plus says. He does seem to ignore the "don't be a dick" rule, that's true; but it also seems to be par for every hole of this particular course.
But whatever. It seems to me that if you don't like those people, there's no reason to get so upset about things they say which you shouldn't care about. It doesn't bother me that Christians think I'm going to hell; it doesn't bother me if atheist plus thinks I'm an "irrational douchebag" or whichever term they like to use.
As for the bit about "redefining atheism" - again, why should that bother you? You know what atheism is - who cares what they say it is? No need to go storming their embassy because they blasphemed the Holy A-Word.
