It's descriptively accurate to say "That person says or does bigoted things" or even "That person behaves like a bigot." But calling them "a bigot" is probably reducing them to a subset of their actions -- which is a common shortcut, but not "accurate."
I agree with minoanmiss that the distinction I'm making is commonly used to derail, though.
As for intention, it matters if you might be interacting with the person. If they intended to act bigoted it's probably a waste of time trying to educate them and you probably want to focus on minimizing the damage from their actions. If they didn't intend to act bigoted, there are other options for how you might approach the situation.
If you're discussing the behavior in some other context, then their intentions don't matter.
