That's a pretty weak argument, and if that's your schtick, you're on pretty thin ice. That said....damn, those old cartoons were racist as hell. What the bloody hell was wrong with these people? To hell with them all, to hell with their Jim Crow cartoon characters, and to hell with all these loser apologists.
The younger generation today doesn't need "Song of the South" to be taught America's shameful, murderous past. We already know. And, besides, that cartoon sucks. Disney's execs are right to bury their bigoted past. They should burn every trace of it so nothing is left - Burn, Hollywood, Burn.
Edit 2:30pm: If anyone honestly believes racism is dead in this country...well, allow me to submit this news item for your consideration:
A move by Minnesota Republicans to repeal school integration laws resulted in heated debate about the decades-long program that aims to diversify schools in the Twin Cities metro area and Duluth. During a floor debate on elimination of desegregation programs Thursday, Sen. Dan Hall, R-Burnsville, said, "I watched Minneapolis get destroyed, so I not only didn’t want my kids in the school system. I took them out of Minneapolis because they ruined our neighborhoods with integration and [de]segregation."
The past isn't dead, kids. It's not even past. The struggle for equality continues.
