i'm not saying that there aren't significant problems with what parrish is saying, it's just that when an established power dynamic exists where one group of people are significantly less empowered than another i.e. the day to day experience of white people *in general* vs the day to day experience of people of colour *in general* those at the more empowered end of the relationship can't really go round accusing those at the less empowered end of the same prejudices they are accused of — accused of most of the time because, either consciously or unconsciously, they're guilty, incidentally.
even if there are some pretty ugly prejudices out there in almost every community, directed to almost every other community, white people claiming that black people are "racist" just doesn't wash or make a great deal of sense. (and even if the not making sense doesn't matter to you, the fact that it makes you look like a knob probably should). prejudice doesn't mean anything at all without the weight of privilege and power behind it. if you're white, calling black people racist is massively insensitive to the history behind the views you find offensive and presents a completely off-whack perception of your own position in this dynamic. put bluntly, parrish is saying white people shouldn't go raving; white american society has dictated all his life that he's a lot less likely to be able to hail a cab, more likely to end up in jail, and more likely to die violently - who's really getting the shitty deal here?
white people calling black people racists (in general) is like straight people accusing gay people of heterophobia or men accusing women of sexism ie totally ridiculous. the only time it isn't is when, as in the case of our last discussion of racism here (a certain poster versus every eastern european immigrant in the uk), it's delivered from a similar position of privilege and power. in that case: "i am english, i have the passport, i've been here longer, you're taking our jobs, you're animals, fuck off back to your own country etc". it's that claiming and assertion of a very real power that made it so bad.
especially interesting here is the fact that parrish's arguments really fall down with his discussion of latino people as white
