If you vote, the people you elect will ignore you. From your position as a private citizen there is nothing to hold your representatives responsible other than the possibility that their salaries and "campaign contributions" from lobbyists might stop. For many of these people they become incumbents because the voting population gives so little of a shit that they'll leave things as they are rather than spend the time and effort to research which candidate best aligns with their goals versus the incumbent. In actual use the only punishment mechanisms that exist have to be enacted by these representatives' direct peers rather than the people they represent, and as there are self levels of self interest that will dissuade them from doing so.

As for being labeled a domestic terrorist, the fools within this administration will use (and have used) any excuse to label someone as a domestic terrorist. In their view you are an enemy of the state regardless, because you are not the state. We are all in jeopardy no matter if we comply or not. If we will be labeled a threat because of any action we take, benign or malicious, then there is no practical fear of being labeled, only being captured and punished.
