This is exactly what I mean. I try to make a point, and you immediately talk about my privilege, without knowing who I am. Well, I am neither rich nor powerful nor influential, that's for sure, nor are countless other people who get increasingly irritated by the sort of language used to describe them and their "privilege". The word "privilege" has been given a completely new meaning in the past years. That's highly problematic. If one group uses a certain word to describe members of another group, but both groups have different definitions of the words, that's a failure to communicate, and that will lead to a failure of politics.
And that is the problem what America is facing right now: A continuous and much-bemoaned failure of politics. Different factions can hardly speak to each other, everybody assumes the worst about the other side, and nobody is willing to give an inch. Republicans are especially bad about this, admittedly, but that's because they feel like they're being put on the defensive. They're faced with a united front of liberals, academics and activists who keep telling them what terrible people they are (or at least that's what they're hearing). Small wonder they keep complaining about liberal media.
The social justice movement has invested vast amounts of time and research into proving that they're right. Good. They are right. Few reasonable people contest that. But no matter how right you are, and how manifest the inequality, you can't keep beating on the same drum and expect people not to get a little tired of you. Not if you don't acknowledge the successes already achieved. You don't need "white history month" or such nonsense to do that. Just take a breath, look the redneck or the Republican or the WASP or whoever you deem privileged in the eye and say: "We've come a long way."
I suppose "marginal utility" was a bad choice of words that made me look detached and, ahem, privileged. The point I was trying to make is that any sort of social justice movement should focus on the "hard" problems. On crime, on drugs, on homelessness, on actual, honest-to-god discrimination and racism. Not on all those buzzwords mentioned in the OP. How many successful black people, do you think, care about the notion that they owe their success to "strong allies to people of color", and not their own efforts? Not very many, I assume.
Most people know how not to be racist, how not to be sexist, how not to be dicks. They don't need a bloody manual. And the ones who do need it will never read it anyway.
