Well, to answer my own question, at your request: I do agree with you that malice is a key element of someone's bigotry. The question is whether that malice is overt or unconscious. There's no real way to determine the latter (unconscious or subconscious), whereas the former (overtness) tends to be more clear-cut; so we can only make those deductions based on additional conversation.

To build on your answer: can someone be bigoted without necessarily having malevolent intent? And, if intent is so essential to the presence of bigotry, how do we measure someone's intent?

So you can see the grey areas, here. If Dave Chapelle was honestly trying to justify "ranking oppressions" in practice -- what is he trying to accomplish, through doing that? Is he trying to functionally center blackness amidst an "intersectional hierarchy"? Or, alternately, was his take-no-prisoners approach intended to get people to THINK and/or get people to ask each other honest questions? I'd concede that the latter isn't necessarily bigoted, but the former most certainly is.
