From my experience, Latino guys don't really care about WMLF relationships and are cool with that, I've never seen white guys and Latinas pick on Latinos anyway.
I think it might suck for Asian guys because WMAF relationships are pretty common and some of them definitely hate white guys for it. It's quite rare to see white men and Asian girls pick on Asian guys though.
Some black guys get really mad when they see women of any race say that they prefer white guys. It's like they see us as enemies and some of them have a very obvious inferiority complex.
The problem with Arab guys is that some of them discriminate against non-Muslims. It doesn't convince me not to love Arab girls though.
No. I don't give a f*ck if black girls or other races want to date white guys or other races. I'm kinda happy people are just finding someone to love in this f*cked up, miserable world we live in. As long as they aren't manipulating or cheating or lying or using or abusing each other, I couldn't care less what race of people are dating who, and I think only idiotic, insecure, simple-minded people would even care. And by that, I mean GENUINELY care.
Sure, I'd get annoyed when women say "they only date white guys" because the unspoken implication is that "all black (or other non-white) men are inferior and disgusting" and it comes off low-key racist. But I only care for about a second and move on with my life. The right one for me will love me as I am, regardless if I'm white or not or if I'm tall or not. The problem is, knowing if those people even exist out there... They may, or they may not. But if OTHER people are happy with each other, I really don't care beyond that. Good for them.
