Why do other Hispanics get mad at Mexicans for giving them a bad rep?

Your CRAZY! There are more illegal Mexicans than all the other countries named above! Salvadorans come legally and if not they get papers faster, within months because of there civil war, and there support on the war on terrorism. Also did you ever think that if Mexico is so great as most Mexicans brag, then why are they here? Why are they the largest hispanic group in the US? Why do they have the most illegal immigrants? I have nothing against Mexicans, they're great people but sometimes SOME Mexicans think they are the best and superior over other hispanics, just how you just expressed your self above.
