So then, if people do not believe in YOUR way of thinking, they are not using their brains?
No, If they cannot confront questions about their beliefs, then they are not using their brains.
Ask me a question about philosophy, evolution, the big bang, abiogenesis, germ theory, carbon dating, whatever, I'll do my best to answer it. Or admit: "I don't know" (And then continue to do research on it.)
I will NOT say: "You just gotta have faith in science." or "I trust science and that's good enough for me." or "That question is evil."
I've met smart theists, like Vinny, who could actually answer questions instead of avoiding them. I disagree with him, but I would never claim that he's not using his brain.
The problem is, they are few and far between, by the very nature of religious faith, you don't NEED to think about it. You just gotta believe.
