You are right. The vast majority of Greek-Americans are true Americans who prefer to drop the hyphenated bulls***. For every wimp like a Michael Dukakis, there is at least a couple of real men like Spiro T. Agnew of Greek background.
Unfortunately, the home country has its share of Commie lovers who are mad that we didn't let Russia take them over. Kinda like our loony left-wingers in places like Berkeley and Eugene, Oregon.
Greece has become a hotbed for Communist groups of all stripes and varying degrees of violence they'ld try. Kinda odd, the birthplace of democracy turned into Commieland.
