My stepfather is a 71 year old African American gentleman from New Orleans. He knows - and all of his friends and family know - that if you see the confederate flag up in front of a house or business, it means "Don't come here unless you want trouble".
Now of course this doesn't apply to every instance where the flag is flown - many people view it as a symbol of Southern Heritage. But it is completely ignorant to think that there aren't lots of people who fly it as a symbol of racial supremacy.
And historically it has meant much worse than that. My high school, Southside High School, in Fort Smith, AR was founded in 1963 - six years after the Little Rock Nine. The mascot was Johnny Rebel, a confederate soldier. During football games, we played Dixie as our fight song and before the 90's, waved the confederate flag at football games. In fact, the interior courtyard of the school was once one giant confederate flag. The practical (intended!) effect of all this was that for African American students living within our gerrymandered school district, the vast majority of them chose to go out-of-district to the other poorer high school. Through our mascot and the flag the local government had achieved de facto segregation without legal segregation, thus avoiding a showdown with the 101st Airborne.
Anyway, I don't know why I wrote this since probably no one will read it but I get really upset when I see something that smacks of Holocaust denial that applies to my native culture.
