Well, I can barely bring myself to respond to you because you insist on waving your profound ignorance like a flag (a big ol' Jello-green flag, in fact), but I'll press on...

"However, if a southern group of say Confederate veterans were still alive and wanted to peacefully march to remember their fallen comrades in a place where from 1860 or whenver they have continually done so, say in Georgia, yes. mg"

Actually, that is a staggering enough admission, given that even flying the Confederate flag in the south is a hugely politically-charged act. But this isn't about people remembering "fallen comrades" - this is a celebration of subjugation and oppression. See, you're trying to rob the situation of its context and its political charge. And you simply can't.
