Why Are Atheists Angry?

[thir]

But it raises a good point. Why do theists immediately say that Atheists are angry for having a different view, and assuming that we don't actually have anything to be angry about with religion. So I ask you, what makes you angry about religion?

The dogmatic part. The part that decides not just what its converts should think and do, but others as well.
I have no problem with non-dogmatic religions.
