Ah, like those "dual loyalist" Jews and "crafty" Chinamen?
I've lived among Mexicans and currently live among Arabs. Believe me, the former is much more preferable to the latter.
I was raised in New Mexico and I count many mexican friends as some of my best. One friend I grew up with graces the Wall in DC, and I make no distinction that his last name was Serrano.He and his four brothers are Americans through and through, and friends to boot.
