Honestly, you're talking about Americans ONLINE. The only interaction you have with Americans is on the internet, and most of which happen to be of the Mestizo ancestry group. Mexico has an average IQ of about 80 and if you look at the border states they're at the low 90's. So in conclusion, about 80% of American 4chan posters are beaners and Mexican-Americans are really ignorant.
Either that or you're just a butthurt Italian that thinks we all think you're Southern Italian.
