Essentially everything that Fidel Castro did as leader of Cuba was opposed to liberal ideals. Liberalism holds that government should protect people's rights both in the political and in the economic spheres. Castro's government has done none of these things. For example:
- Castro closed down newspapers that were opposed to his revolutionary ideas.
- He banned labor unions.
- He got rid of teachers and professors who were not supporters of his ideas.
- His government made most forms of private enterprise illegal.
- Because of this, something like 90% of Cubans work for the government, which is not what liberalism would prefer.
By doing things like this, Castro acted in ways that were completely contrary to liberalism.
