Not that I'm defending the Black Panthers, but the Klan does have the whole traditional garb that they wear when burning crosses and attempting to intimidate others. It makes them easier to identify. It's hard to pick a Black Panther out of a crowd by the clothes he wears, unless he's got a t-shirt on that advertises the affiliation.
Yeah Noonie, they blend
