forget trump, try calling a state trooper an ass next time you are pulled over and see how that works out for ya:)
you are allowed to criticize or insult trump because your criticism or insults hace 0 influence on anything. Regular chinese person talking shit about the govt is taken seriously because thats not something anybody does and will attract a lot of attention from other people and can result in a problem for the govt. if your words had potential to create serious problens for American government you would have been silenced very quickly.
