Queen Latifa is allowed to be racist... if she's funny

Beauty Shop is a spin off of Barber Shop a movie about a family shop in a black neighborhood trying to survive while a commercialized mega hair salon moves in across the street. Barber Shop uses wit and satire to talk about real racism issues. The characters debate issues and put everything in context. Where Barber Shop succeeded, Beauty Shop crashes and burns. It is probably the most racist movie I have ever seen. Every single white character is a harsh stereotype; including a flamboyantly guy man, a southern white trash girl trying to act black, a naive uptown women who gives her keys to a random black man on the street thinking he is valet, and a racist uptown b-word. The white trash wannabe works in the beauty shop and is continuously ostracized because of her race. Every time the other girls are laughing and having fun this lone white girl tries to play along and is stopped because she obviously can't talk with the black girls. They even get upset with her for using Denzel Washington as an example as a good love scene actor. Like she doesn't have the right to bring up a black actor. Throughout the movie they shoot her harsh looks and say "funny" things about how she doesn't understand. Switch the races. There is a movie about a bunch of white girls leaving out a black girl cause of her race, making racist comments. Comedy? I think not. I read an article on the web about the movie and they sited the "funny reverse-racism." Like racism against white people isn't racism. I understand that all and all the minorities have dealt with A LOT more racism than your average middle aged white guy, but does that excuse it? Is that what Beauty Shop is trying to do? Even out the racism?
