The political government is composed of more than Fidel Castro. Namely, the Cuban Assembly, which holds and practices most (if not almost all) of the power in Cuba:
http://members.allstream.net/~dchris/CubaFAQDemocracy.htmlI would like to see what "repression" you speak of, because dissent is very much legal in Cuba. Dissidents have held rallies in Cuba recently without any intervention from the government. If you are talking about anti-homosexual policies, that is a product more of the homophobic culture of Latin America than anything else.
You would not agree that people from one country condemning another country for (fabricated) human rights violations, while their own country is involved in FAR more atrocious activities is a bit ridiculous? People need to recognize that Cuba suppresses dissent no more than the US does (arguably less), and if they are blind to this, that is pathetic and sad and I will point that out to them constantly.
