> If someone was wrong, I wanted them to know it, and I wanted them to know exactly why. I collected counterarguments the way I collected patches. I believed that if I just laid out the logic clearly enough, the other person would have no choice but to come around. Truth would win.

This is probably how flat earthers think. If you engage in arguments without being prepared to be proven wrong, and you're hoping people to accept your argument as truth instead of both of you arriving at the truth together, you're not debating, you're being eristic (which is a fancy word I just found).
