People who are trying to start a pogrom on trans people, Jewish people, etc should be prosecuted actually, regardless of whether they’re actually successful. You can’t wait for the nazis to win before you crush them, by that point it will be too late.
Two wrongs don’t make a right. If we go that route we are going to become the thing we are trying to prevent.
What about these countries governments are different structurally from Cuba’s government?
Rather than a difference in government structure, I would point to a difference in leadership. I personally believe Castro really did believe in socialism and had the best interests of the Cuban people at heart. As great as that is, a system of government that depends on the benevolence of its leaders is not one I want to live under.
