Nothing about those situations are comparable. The president of the USA is democratically elected. The USA is ruled by its own government, not the government of a foreign country (which a huge amount of Hong Kong citizens view China as), the citizens of Hong Kong don’t want to overthrow their government, they want to protect themselves from clearly oppressive regime, the USA has a rather impressive set of constitutionally guaranteed rights, citizens of the USA have access to a robust legal system. There is nothing about the situation in Hong Kong that compares to any level of dissatisfaction you believe may exist with a democratically elected government.
