I didn't say that, don't put words in my mouth. I said that there could be other factors outside skincolor. I am aware of that racism exist, who the hell ain't.
Are you aware of the fact that we judge and discriminate people all the time based on looks? We are constantly in a selective process in social situations where we modulate our own behaviour in response to how attractive, innocent or dominant other people look like. Studies also suggests that there is a truth to stereotypical facial characteristics, people who look more dominant are for example more likely to cheat. We're animals for christ sake.
A higher fwhr in a man makes him look more dominant as previously said and this is attractive to many women. One study found that the us presidents have all had higher than average fwhr for example.
I suggested that MAYBE fwhr varies among ethnicities and if that was the case, it could further explain why some people is being perceived as more threathening. The truth in this case is obviously that I don't know. I'm just curious.
