My point therefore, was that "freedom of speech" only extends so far.
That must be why 44% of black folks in Mississippi voted to keep the stars and bars on the state flag. You see, unlike you, they understand that the WONA was fought over more than slavery. They have ancestors who fought and died in that war also.
And your definition of free speech stinks. Under your view anyone who is offended or has their feelings hurt [even though it might be because of a knee jerk reaction] has the right to deny the right of others to express themselves. Well frankly abortion offends me, but I don't see anyone rushing to gag those murderers.
And as far as treatment of slaves went, its true some people were treated badly. The 500,000 slaves that came to America and lived throughout the north and south had a tough road--but you know what? It could have been worse for them. They could have been sent to the middle east where black men served as Eunichs and were subsequently castrated so they couldn't procreate. So instead of always focusing on how naziesque the south is, why don't you try getting a clue.
