Why do most republicans steriotype liberals?

It's very convenient for them. When they don't have a sensible argument for anything, they start pulling about the labels, and slanders. According to them, no "dems" work. According to them "dems are on welfare". According to them "all blacks vote for dems". According to them "all blacks are criminals, and should not have guns". According to them "blacks are uneducated". And then they wonder why more blacks don't join their 'party'. But I guess they're hoping that Steel will win more of them over. Which I doubt very seriously. Both 'parties' have some sh...t with them. But that party takes the cake and the icing as far as anger, racism, and bitterness, selfishness, and lack of diversity goes IMO.
