When Trump actually starts ordering mass killings, we can talk.
At that point it will be both too late and no longer possible to talk.
Let's be honest, though. If Trump did that while in office, he would not only be immediately impeached; he would be arrested.
I like any strategy that might give his supporters pause, but if we're being accurate, I think a better parallel to Trump would be Marine Le Pen and the National Front in France. He's a post fascist, in the sense that he would presumably try push democracy to its limits while working within the boundaries of constitutional government. I don't think he would try to fundamentally change our system of government, and if he did, he would fall flat on his face.
