You are narrowing in on the left's main deception: they sell their politics as morality. Therefore, if you are against their politics you are immoral in their book. They largely succeeded for a number of decades so far in this trick and have largely relegated dissent to the doghouse. Today there are outposts of dissent that are popping up in the mainstream and the left is just exploding at the seams with anger. For them this whole charade is a zero sum game. You either believe their politics is morality or you blow the whole thing wide open and they lose.
