I think it’s a part of American racism, when they put labels on people according to their race. For example, they say blacks should be big, muscular, with low IQ and Asians should be weak physically with high IQ and whites are average in everything. According to most researches, blacks don’t have bigger dicks then whites. Also, if you browse slut websites like stripperweb.com in their forum they say that there are lot’s of blacks and whites with big and small ones, and those girls are hoes who did it with everything that moves. So instead of researching this kind of stuff through porn, which is a business of selling stereotypes, people should think outside the box and understand that those are just labels generated by mass media.
