So the US should relax immigration standards and admit 1.2 billion Chinese? However bad Castro may be, he's nothing compared to Mao and his descendants in terms of communist butchery. Why do Cubans get in and Chinese don't?
Thanks for your hypothetical discussion, but there are real Cubans *today* who are escaping from Cuba and our response to them has very real electoral consequences. If conservatives were to block these refugees from gaining residency about 1 million Cuban-American votes for Republicans in Florida would vaporize instantly. This would give Florida to the Democrats and could very likely put Hillary in the White House.
I should also note that I find it interesting that conservatives here are bashing the strongest anti-communist portion of our population. These Cubans who escape Castro aren't communists, they are individualists (almost by definition). The political pressure to keep the embargo on Cuba for almost 50 years (and deservedly so) has come primarily from Cuban-Americans in Florida. If they are willing to keep their focus on a communist threat for almost 50 years, shouldn't you give them a little respect as conservatives?
