I disagree, but also..

..please define a 'white' person, being as scientifically accurate as you can. Truth is, it would be nigh on impossible to find a single person on the planet that is not a genetic mixture of one sort or another.. there is no 'purity' to speak of. Brown skin can be very attractive, but not only that, I think the evidence is in to show that 'racial' mixing (also a bit tough to define accurately) is generally beneficial to any gene pool. Certainly, the lack of mixing results in genetic errors that get worse and worse over time.. just ask the orthodox Jews. I read only recently, but already sorta predicted prior to that, that even modern humans and other non-modern humans like Neanderthals were interbreeding, and I'll go so far as to guess it was because of love.
