Yeah, we remember. And thanks to the attitude displayed in your comment, these complaints were not taken seriously. until these specific Italians ended up with control of massive illegitimate industries, gambling, and loan sharking, ran protection rackets that victimised and intimidated thousands of legitimate small businesses, and murdered hundreds of innocents.
...which was finally ended by the RICO act; which is almost certainly unconstitutional, but has been allowed to fester b/c the Mob was (so far) worse.
So people should have been discriminatory against Italians? What are you getting at?
