Let me tell you genetic facts:
Black people have very curly hair, dark skin, large teeth, big bones, flat noses, full lips...maybe more testosterone...
I agree with what you said against the racism. But to take you up on what you just wrote ...
If black people have more testosterone, then howcome they tend to be quite hairless ?
Black people tend to be quite big, it seems you relate that to them having more testosterone. Is that so?
Jews tend to be smaller than the average population, are you saying they have less?
If so, then part of you is an anti-semite, or a self hating jew, or a "self hating whitey". Somebody who thinks blacks are more masculine. Let me educate you. If you use google, you will see that Black people do not have longer members than white people. And I wouldn`t even conclude that they are stronger either(they just have a slower metabolism, so they get HUGE and that helps them to have the energy to workout and build lots of muscle. But they only get that if they workout). And they are not a hairy people. They are pretty much hairless. And they can sing really really high.
Notice how the black rap culture, they act like arrogant 10 year olds. Testosterone does not do that. Testosterone can turn you like that guy in "The Renegade", it can strongly affect your personality for the good like that. It can turn you into Bruce Lee, if you have the brains. And it can turn you into a Kahanist. It does not make you steal. If you don`t realise that, then maybe you need some. But don`t insult those that have it. And you are, by saying that blacks might have more.
