The Confederate flag has clearly become a racist symbol.
It is legal for people to display it all they want.
It does not send the message "My greatgranpappy defended his grits factory and cornpone mill against them Yankee invaders". It means "I hate them n*****s, they got too much awready".'
If I were a fan of the flag, I would still not stick it on my bumper. It would educate no one, inform no one of anything worthwhile, and could likely mean that my car would get keyed.
Bumperstickers are by and large not worth the trouble.
But people have the right to display their intolerance.
and every damned thing I said about Forrest was true. He did sell slaves, he was the only CSA general who rose all the way to general through the ranks, he did order the massacre of Black POWs at Fort Pillow,and he was one of the main founders of the Klan.
He mysteriously abandoned the Klan, though. Perhaps he was threatened and not as brave as his reputation.
