Straight guys like so spread their seed... As much as I agree with what you posted one thing is getting laid or dating but when it comes to getting serious or considering someone as a potential mother of your kids most guys do care about ethnicity.
I'm amazed about so many Asian girls who only date white guys. One of my nephews loved dating girls of that background because they treated a men in a proper way, they didn't fuck around with other guys and they had tight pussies but refused to marry any of them because he wanted his kids to be white because "white is beautiful". I'm just repeating what HE said.
