why are they such meanies??

Why are emigres from places like Cuba or Vietnam so often the most strongly in favor of hardline sanctions? You know, the kind that make the people there miserable without doing anything to improve human rights. Either I'm totally confused about how sanctions work, or people who come to the U.S. from places with shitty governments tend to go off the deep end, like Ayn Rand did.

In any case, at least this might be starting to change for Cuban-Americans, since the ones who have family members in Cuba care a little more about conditions there.
