He has a deep prejudice against a group of people based on questionable reasons. In my book, that makes him bigoted.
Indeed. You can be nice, but hold a bigoted opinion.
''A bigot is a person who is intolerant of opinions, lifestyles, or identities differing from his or her own, and bigotry is the corresponding state of mind. Bigot is often used as a pejorative term against a person who is obstinately devoted to prejudices even when these views are challenged or proven to be false or not universally applicable or acceptable.''
By that vague definition probably 60% of all humans are bigots.
I believe it.
That definition kind of washes out the the definition/negativity of the term. Wouldn't you say?
Just because every privileged harms the oppressed doesn't relieve them of responsibility for it. Of course far more than 60% of whites are bigots, but it is a bit silly to apply the term to the oppressed races - the unpleasant effects only travel down the power pyramid, not up.
