Christianity, Islam and Judaism, are generally regarded as the only major monotheistic religions in the world today, though each of the three has multiple sub-religions, some that differ from each other widely enough that they could rightly be called religions unto themselves. Incidentally there are small monotheistic religions outside the Abrahamic religions.
Traditionally, less tolerant members of these groups believed that the members of one or more of the other groups are evil and need to die.
All three of these groups include sects that are hate groups because they hate each other. The one thing they can agree upon, however, is that they hate atheists more, presumably because atheists are smarter than them, and demonstrate that fact by not trying to kill each other.
