let us say, just for the sake of argument (i don't really believe your ignorance), that skin color and race are correlated somehow
it's a bell curve. you understand that, right?
so, for example, we have on one end one of the most cerebral presidents we've maybe ever had, at least since wilson: barack obama. obviously more intelligent than the vast majority of white people, as well as black people. more intelligent than people of all races, period
what is the value, exactly, of saying that because his skin is brown, that we have to ascribe some sort of negative modifier on how we perceive his intelligence, just because a bunch of other people who are brown are supposedly less intelligent on average?
intelligence is an INDIVIDUAL value. it does no good to class all people according to an arbitrary signifier. if you were interviewing a bunch of people for computer programmer, and disregarded the ones with brown skin because they were "less intelligent," you might have hired a dumb white person and disregarded the black genius. it does no good to you, nevermind black people, to use this shallow useless prejudice, because it doesn't actually help you. an INDIVIDUAL assessment is what matters
for example: most african americans have scottish, irish, english, etc. blood in them, because a lot of their forebearers were raped. therefore, a lot of white people were doing a lot of raping. therefore, according to racist "thinking," we should assume all white people are rapists, because we can prove they rape a lot ( i don't believe this, i'm just demonstrating your ignorance to you)
i'm not really sure this argument is worth having with you though, because i doubt you have enough intellectual capacity to appreciate the argument, since it requires a low iq to believe in racism. by believing in racism, and all of the logical fallacies that come with it, you have objectively proven to me that you are a stupid person. i don't respect you
