I say it's never going to happen. As long as someone can point out yet another example of how whites hate blacks, racism is never going away.
A few years ago, a hangman's noose was just a hangman's noose. Don't let anyone see you with one, now. A hangman's noose is a simple and very useful knot and when I first went to work in the oilfield used them all the time for various purposes on my trucks. Not long after it became one of the hallmarks of racist symbolism, I was told, in no uncertain terms to cease and desist. Today it's a noose, tomorrow it'll be a hoe, or a rake, or what the hell ever. I'm waiting for someone to claim that a mule team pulling a wagon is racist, because slaves hauled cotton out of the fields with the same kind of equipment, or a mule is some referrence to, "40 acres and a mule".
Racism ain't never going away and as long as you continue to beat up on whites for every little chicken**** perception of racism you gaurantee it's survival.
