Unless you spend long periods burying your nose in badger shit, or performing anallingus on garter snakes, one questions the source and believability of your claims about my personal hygiene
There are these inventions and conveniences of modern society, which you may have heard of called soap and shampoo. There's also this marvelous thing called indoor plumbing, which facilitates the operation of a cleaning apparatus known as a shower.
I use both frequently, and make it a point to keep my dreadlocks clean by washing them approximately two to three times a week with this shampoo, much like most folks. The stereotype of the "dirty hippie" doesn't apply to all, thanks. Need I remind you of the infestation present in Bob Marleys dreads when they were posthumously cut open? He's half black. What bearing does race have on personal cleanliness? Or is it easier to poke fun at the white people with dreads for fear that a black person might subject you to a severe ass kicking or dismemberment when confronted with your ignorance?
