The fact that Cubans were forcibly barred from leaving the country during Castro's time in power would seem to contradict your opinion. Despite that, 20% of the Cuban population risked their lives to flee during Castro's days in power, and they are only the ones who had the courage to risk death - many others longed to flee.

As was the case with the Berlin Wall, it is rather hard to make the case of how beloved a particular leader or government system is when a significant portion of the population has to be forcibly restrained from fleeing.

Yes indeed, facts do remain as facts.
