You're Fine. 'Rican here, and while I appreciate Cuba's socialist history as well as the historical cultural bonds that Cuba and PR share, you really don't have to feel obligated to move back or anything.
I, and a lot of others, would argue that Cuba as it stands now isn't socialist anymore either. It went the revisionist route of most 20th century socialist states and was likely the victim of Krushchevist social imperialism. Performativism doesn't accomplish anything, anyway.
Besides, I'm sure people here need you more to help spread a leftist influence and raise class consciousness :)
