You mistake the traditions that has kept the nations of the UK together and strong, as being anti-democratic, when that Conservative tradition promoted freedom through stability.
You said you have more freedom of speech. So what can you say that I cannot?
As for the Cuban point. So no US citizens would like to go to Cuba. Your point seems a bit Leninist to me. It would be great to see what you would say if Britain refused it's citizens to travel to certain countries while US citizens could go anywhere. I can hear the cry of "unfree, unfree"! :)
Some U.S. citizens want to travel to Cuba. Some do so legally, some do so illegally. The Cuba embargo is not unanimously supported here, which should be no surprise. There are occasionally discussions in Congress of ending the embargo. Pres. Bush gave a fantastic speech on the subject, saying that the Cubans themselves could end the embargo instantly by holding one free election. Of course, an embargo is a collective act. If everyone decides for themselves, then it is not an embargo. I am not saying that there are no good arguments for ending the embargo. My point is that an embargo implemented by freely-elected representatives of the people is not "unfree" or "Leninist." It is just a public policy of a democratic state. Business as usual.
