That’s silly. Everyone here originated with immigrants. Illegal aliens, people who break our laws, are despised.
Actually, we support rule of law. We just abhor people who sneak in the backdoor illegally, then demand recognition and amnesty (including welfare).
People who are dishonest and cheat are neither respected nor wanted in the U.S.A.
I agree it’s silly, but nonetheless the perception exists. I’m somewhat mystified by it, it makes no sense, but it’s there.
