"Racist" lol  That's really funny.  There's a hell of a lot of difference between going to a salon to have one's hair groomed and going to extraordinary lengths to torture one's hair into a style for which it is not naturally suited (the way lots of black folks endure all sorts of crazy chemical crap to perm their hair strait).  And, yes, there are some white folks with really curly hair  including some with African ancestry who have nappy/frizzy hair who do dreads without resorting to home crafting techniques and snatching hair off the backs of sheep.  But they're certainly in the minority.  If there's a single photo of dreadlocks in an article dealing with the subject  my opinion?  Hell, yeah.  It should be of a blackman/woman.  Same thing with an afro.
