Theology? expertise? its just reading lots, making up stuff then arguing about the made up stuff!
Well of course it is. But if you're going to attack the daft things people believe in specific detail, it helps if you actually know what it is they believe, and how your arguments have previously been addressed within that belief system.
It's like someone coming on here saying "How can Judge Rico still be appearing in the comic, he was killed way back in Prog 30, can't you see that if you believe
that then the whole Judge Dredd thing must be a load of made up twaddle?". We get
annoyed because we know, and anyone who had done their homework would know, that it's a different Rico - and in the process have grounds to ignore and/or reject the sound important fact: that it's just made-up.
It's a bad approach: religious nerds are still nerds, if you troll us do we not froth?
