I'm not going to say that there aren't atheists that hate Christians. I've known some. But just as there are atheists that hate Christians, there are going to be Christians that hate atheists. No matter what group of people you have there are always going to be those that hate against them. It's human nature. However, I don't think most atheists have a hatred against Christians, and I think a lot - a lot, not all - Christians take an atheist's lack of belief as hate. That's just not the case.
And as far as atheists expressing rage against god, that's a little ridiculous because they have no belief in a god, how can they possibly hate or dislike one? If you have any emotion towards a god then you are, by definition, not an atheist.
