there's a few more black people in the link as well
not relieved, but on boxden I thought they couldn't be racist
I've seen the other tweets. I follow the blog that originally reported it
as for any "intellectual" discussions on boxden (which I do my best to avoid reading), I'd imagine the two sides are operating with different concepts of racism. In some circles (ie. academia), racism might be defined as "a highly organized system of 'race'-based group privilege that operates at every level of society and is held together by a sophisticated ideology of color/'race' supremacy." ()
and on the other hand, you have people who might simply define it as any kind of racial hostility. so if somebody says 'black people can't be racist', they're most likely inferring that black people aren't engaged in the former definition.
meanwhile, for somebody whose d!ck gets hard over these kinds of tweets from black people (in hopes that they'll take some heat off white people), they're most likely inferring that can black people, too, can be engaged in the latter definition
