Jim Carroll has a wise statement to be heeded, here.

"does that mean that to be 'religious' is a bad thing, or just that it is 'bad' not to ascribe to the same religion as they do - do tell?"

Suppose that atheism is considered a religion, (I don't think it's true),
wouldn't it be intolerant and bigoted not to accept it as equal to any other religion?

If it is considered "fundamentalist" then those who make that accusation should examine their role in enabling Christian fundamentalists or fundamentalists of any denomination including Judaism and Islam.

There are some Christians who speak out against the fundamentalist aspects of their religion and do it well. Instead of going after atheists, Christians, Jews, Islamists, Spiritualists or whatever would do well to go after those in their own religion(s) who they consider fundamentalists and leave atheists alone, including Dawkins who has been misrepresented here. Most of those who criticize him have never read his books. He has stated his views succinctly and no one is required to accept them without examination. But ad hominem attacks against the man is doing a disservice by polluting the discussion.
