Are all atheists this ill-informed about religion?

[Esquilax]

That there are apparent wide and important differences is not being denied. What is being denied is that these are differences of core doctrine. Rather they are differences in peripheral doctrine or practice. 

So... I just want to be clear here: the length and breadth of your argument is "atheists are ill informed about religion because it is my personal opinion that the differences they see aren't a big deal"? Really?

Because, see, when I see different denominations arguing about what it takes to get into heaven, my first thought is not "this isn't a big part of christian theology."
