Distinguishing Between Fact, Opinion, Belief, and Prejudice

A fact is verifiable. 

Unlike an opinion, a belief is a conviction based on cultural or personal faith, morality, or values...) 

Another kind of assertion that has no place in serious argumentation is prejudice, a half-baked opinion based on insufficient or unexamined evidence 

I think, like most, if not all, of Lone Wolf's comments.
