I asked him about two things: the 9/11 conspiracy theories and God.
He believes in God, he thinks 9/11 was 100% a terrorist attack.
Then I asked him, why don't you believe the 9/11 conspiracy theories (which have some, although often rather dodgy, evidence) compared to believing in God, where it is all belief?
He ignored me

(I'm not really saying whether I believe in the 9/11 conspiracy theories, I'm sort of 50:50, but I don't believe in God)
