A very left leaning friend of mine despised Castro and loves America. His father was jailed by Castro, his grandfather was the first Cuban to win a gold medal in the Olympics (and later became the sports minister of Cuba ...before Castro). His father later served in the Mission Control center in NASA-JSC with my father. A complete USA patriot regardless of his politics and his Cuban flag.
I find that many of the Cubans who came over very early are mostly assimilated. They are also the ones who come up and tell me that they are really Spanish, not Cuban.
