LOL! Stereotypes exist for a reason and I'd say more than 75% of the time they follow through. Mexicans from Mexico throw shitty toilet paper in the trash can. They use vinager to clean everything. Just generally not as smart as some other cultures. Sure theres exceptions.
I'm not racist but I'm not going to ignore the obvious points sitting in my face just to be politically correct. Gringas don't like them because they don't know anything about American courtships. I don't know if they bark and whistle at girls in Mexico but I can't see it working there either. They're just not as refined.
