That's what common white guys say. Black guys say **** about white girls, too. It's more hurtful to black girls, tho, since there are more white guys than black guys in US and Europe.
Basically, everyone is ****** to people that are different to them. That's why we have sexism, racism and homophobia. People are crap and if you give them power, no matter their race and gender, they will always abuse it.
