Yes, that’s all true. But that’s a good argument for “You shouldn’t only vote,” not “You shouldn’t vote.” See the difference?
If the only action we take is voting, then the tyrants who aren’t constrained by law will win. If the only action we take is direct action, then the tyrants win as soon as they outgun us. If we use voting to advance things in civil society inside the lines and direct action to keep the tyrants playing inside the lines, we win.
Not sure how to tell you this, but the Right has spent years and millions of dollars trying to make voting illegal for its opponents.
So… I guess it does change shit, by your definition.
