You make it seem so nice when you say "the author as an advocate for a fairly specific set of political and social beliefs." But let's be honest, the author is a racist. I get his frustration. But his remarks make it clear he dislikes all white people. The entire "dumbwhite*" stuff, the white supremacy comment, the white men feeling they have authority, etc., are all examples of a negative feelings held against white people simply because they are white. This is racism.
It can't be okay for him to be racist in response to the racism he was experiencing. If we're being asked to not accept one form of racism, then we have to not accept any form of racism.
This is another form of white privilege, white people weighing in on what is and isn't racism. White people are the people least qualified to talk about this. Most white people are completely blind to racism except in the most egregious cases. (Spoiler: those are among the least common.)
And let's face it: white people are, by far, the ones who dole it out most often and virulently, the minute they feel threatened by a "thug" (a black man who is either arguing passionately or wearing baggy pants).
All in all, I'm willing to cut this guy more than a little slack! He probably got a more thorough education about the politics and dynamics of race in the first N years of his life as a black male than most white people get in a lifetime.
It's not white privilege to be able to weigh in on what is and isn't racism. It's the privilege of every person, regardless of race, to have an opinion.
Do you have evidence to support your claim? Are you talking about pure numbers or per capita? Are you limiting your numbers to a specific country? Do not use numbers as an argument unless you have actual numbers to back up your argument.
Him being a racist doesn't mean the white people he was interacting with weren't racists too. I'm just saying that it becomes a factor in his credibility, because he makes it obvious that he did not remain impartial while working there.
And, again, if you're going to tell me that racism is bad, you can't do it while being a racist yourself. Well, I suppose you can, anyone has the right to say what they want, but you have to at least acknowledge the hypocrisy.
He wisely documented all the abusive incidents. He doesn't need to "recall" anything.
