"By definition you can't learn about religion either because the only thing required for religion is to believe in it."

That is a very weak argument. One cannot learn about religion because all you have to do is believe.. and since I don't believe, I can't learn it?

Edit: so there is no proof or evidence needed for religion – you just have to believe. Would you like to buy this rock i have? it keeps tigers away...

I'm glad you agree that it's a weak argument. It also just happens to be the argument you made in reverse. That was actually the point.

No, he's deliberately misreading me in order to feel that his self-identification is infringed upon.

According to him, if a Christian believes in God, and then reads about Christianity to learn about Christianity, said Christian is not a Christian because they're "learning about Christianity". The sheer quantity of stupid required to believe this has disinterested me in continuing any conversation.

I agree with you, the point of my post was to try and get him to see the ridiculousness of it by simply reversing it.
