Not entirely. Because various atheists atheist in various different ways. Some atheists -- whom I and many other atheists call New Atheists -- have some tendencies which are reminiscent of religious behavior. Like repeating a handful of quotations over and over and over and over and over and over like fundies quoting their favorite half-dozen Bible verses. Like being blind and deaf to valid criticisms of Dawkins, Harris, Hitch & co the way that many religious believers simply refuse to see flaws in their leaders.
And of course, some atheists actually meet on Sunday mornings in places they call atheist churches, with services sometimes led by ex-Christian preachers. That's a particularly obvious way in which atheism is sometimes like a religion in some ways.
Some atheists, including Dawkins, Harris, Hitch & Myers, are unfortunately quite Islamophobic in a manner strongly reminiscent of Christian fundies.
New Atheists and Christian fundies share a profound ignorance on historical topics combined with an unceasing flow of clueless remarks about the history surrounding Biblical topics, New Testament and Old.
Seriously, New Atheists: if there wasn't quite a lot about you which reminded people of the fundies, do you really think that so many of them would say so often that there is? Astonish me: come to grips with some piece, any piece, of valid criticism aimed at you. Admit at long last that some of your critics might have had a point now and then.
