>niggers are more violent due to higher levels of estrogen,
A man who has higher testosterone levels, will also have higher estrogen levels. The body balances these two against each other. That's why when a man takes steroids, his body will start producing more estrogen, and once they stop taking steroids, they are often screwed over completely (some even end up becoming trannies).
>Estrogen is also linked in men to higher sexual desire
Like I said above, a man who has higher levels of testosterone, will also have higher levels of estrogen. What is more important is the balance between testosterone and estrogen and the balance between testosterone and cortisol.
Generally speaking, when a man's testosterone level drops, he will have a lower sex-drive and vice versa.
Niggers dominate sports that require pure (explosive) strength (I.E. testosterone) like boxing, basketball, sprinting,etc
While Whites dominate sports that require technique, intelligence and stamina like cycling, MMA, racing, etc. (also things like snooker, darts, etc.)
>Niggers are not alpha in the slightest.
The average nigger has fucked more women (and has more children) than the average White man. That makes him in pure biological terms "more alpha". A Gorilla or a bull also has higher levels of testosterone than a White man though, that doesn't mean they aren't inferior.
