You are setting up a false dilemma. The position that "if he is unwilling to stay in the US or go to the people who will just return him there, so he can face serious punishment", aka that if is unwilling to become a martyr, then he can not be a person who actually wants to point out something wrong. This is a silly scenario. For example, I we need to fix the prison system in the US. I am not willing to martyr myself for it. Is it your position that it can't be too bad then? Or that I must not mean it because I don't want to be a martyr? The premise from which you are arguing is just incorrect.
