just because they aren't fighting for -YOUR- concept of freedom, doesn't mean they aren't fighting for freedom
Which is exactly why I cited examples where any rational person couldn't get it wrong. Nobody who is fighting for the power to take away other people's freedoms (say, of speech, assembly, religion, etc) is fighting for freedom. It's possible to objectively look at two different fights, and see where one is actually about freedom, and the other is about gaining power to deny freedom.
Your knowledge of the revolution and the governance of England is also rather lacking.
The governance of England (not to let it off the hook there, even so) was not the same as England's governance of the colonies. Don't tell me to learn more about it when you paint with a brush so broad you miss out on that reality. The Americans were fighting to be free of how England was ruling the colonies. Even if you consider the then-state-of-affairs in England to have been the model of freedom (plainly not true), the colonists did not enjoy the same liberties or representation.
That's not to sugar-coat the man Che became and his eventual ruthlessness.
"Became?" He started out that way, and didn't stop. He was no champion of a constitutional democracy. Didn't seek one, and didn't act to establish one. What he and dictators like Castro found to dislike about the regimes against which they rebelled has nothing to do with their vision for a totalitarian communist paradise. They set out to achieve what the Castros have been using violent oppression of their own people to preserve ever since.
If they were ever about freedom, they wouldn't need to lock people away or simply kill them for speaking their minds.
