So I can't believe I didn't think about this earlier - I really hate white people who wear their hair in dreads. And I'm going to get right to the point here and not dilly-dally around the root of the issue. Dreads on white people are really gross because the texture of white people's hair makes their hair look dirty more or less after one day of not washing it. That's the reality. The texture just does not accommodate this look. If you're white and you wear dreads, your hair will inevitably look dirty, greasy, and unkempt (I get that that's kind of the intention with dreadlocks, but white people hair looks particuarly bad when left unbrushed for 11 months.)
I, for one, could never wear dreads, even if I wanted to, because (let me give you an example) my hair will be dirty by the time I wake up in the morning even if I've washed it the night before. So just imagine what that would look like a million times over: pretty grim, isn't it? By the time my hair would even form the dreads (if it could even do that is debatable because my hair is so freaking thin), there would most definitely be animals or insects nesting there and/or an oil slick would have developed. It's really an unattractive concept.
And I am all for self-expression, etc., but I also can't help feeling that white people with dreads are trying to present an image of themselves as something that they're not. Disagree if you will, but most of the whities with dreads that I've met have all turned out to be HUGE posers. Maybe it's just those few who sully the good name for the rest of the white-dread-wearers; maybe not, but I am going to stand firm on my belief that white people should stay away from dreads at all cost. There's just something icky about it - both to look at and the general vibe that it gives off.
