Though racism is not tolerated now and then in everyday life, in TV & Film it is usually uncensored and goes by unnoticed. I think that black/coloured people can be sensitive and even people of Caucasian can be too.
This episode proves that sometimes the Goverment and other people can just go way too far when it comes to racism. Cartman lobs something at Token (or something like that) and gets done for " Hate Crime " which is kind of lame.
I like the part with the sled race at the end though. That was good. ;D Memorable, but not so great.
