I haven't heard this. Atheist don't believe in any religion and that's all. They don't hate nothing. At least the normal atheists. Then there are extremists (as in every kind of this things) that hate something or everything. But this is not to be generalized.
I thought that Atheism is just like any other faith and now I see they have even many denominations.
As I recall, there's an article I read about the different types of Atheism (I'll look for that blog site).
1. Intellectual atheist
-They like debating and arguing, particularly on popular Internet sites.
2. Anti-theist
- This group regularly speaks out against religion and religious beliefs, usually by positioning themselves as "opposed to religious ideology".
I forgot the others.
