It hasn't been done away with so long as you pretend you're stuck in the past. It's as if you said Germans are Nazis today, still.
My grandpa did both world wars, some second family of mine got put through the nazi death camps, my father got the racist treatment all along his studies and career... I got it too as I grew up.
What do I have to gain from ringing the sufferance bell to no end, weeping past pains that are in fact self-inflicted?
That's right, you only feel as much pain as you allow, yourself. If you are doing the right thing, you should feel no pain. Nevermind "feeling" pain when someone says a magic word... How does that work? Does he have telepathic powers to flick on the switch labeled "pain"? That's a load of horse****.
The whole 400 years oppression and just 40 years ago is just statistical appeals. The same way
You go to any college or university and refer to Black people as the "N" word, colored people, or Negro...you will get corrected and asked not to refer to them that way.
could be an appeal to ridicule or popularity, or tradition. None of these are rational.
It's not that it shouldn't be talked about.. The Germans still talk about the Nazi era (in fact almost obsessively), but you don't see them or anyone else in the world systematicaly shaping their perspective to be opposite the Nazi point of view. If you really do not care about something, if you're truly indifferent to it, you don't even account for it. You don't polarize yourself to it.
But that's what you're doing, you're keeping everyone in a mindset that's dated and obsolete. It's not the 60s indeed! Stop acting like it is. Slavery is over, racists have no rhetorical authority whatsoever, and mimicking them in a mirror counter-racism racism isn't going to help at all. It isn't a "good thing that's happening in our country", it's a self-inflicted stigma.
"Scars and suffering"

What do you do, cry every morning? Should "white people" (e.g. Bustr, right??) flagellate themselves every day to balance out today's "scars and suffering" supposedly born by people decades later?
Lighten up.
That's right, just forget about the past and just live life.
Yep, that's exactly it. Move on. Living well is the best revenge. Carrying on suspicions and self-fulfiling prophecies isn't.
Where would I be today if I had stopped to contradict and refute every single racist and bigot I'd run into? I'd be nowhere. I'd never have made the top of almost every single class I got in, I'd never have skipped two grades, I'd never had the lucidity to just ignore the ****in racist teachers grading me down despite handing in the very best homework and research (sometimes in the whole school), I'd never have enjoyed going out with girls of every creed and race, never have grown out of the racism-tropic mindset.. I'd never have been everything I could be, and instead would have been no more than allowed by a centrism to the bull**** that is racist bigotry.
Nevermind if I'd stopped and

everytime someone said something nasty about me...
