I think the disconnect here is coming from the vague "bad things" and "dragging people from their homes."

To me dragging people from their homes conjures up images of Krystalnacht, when the nazis dragged people from their homes for ideologically disagreeing. Ideologically disagreeing isn't "bad things" enough for me to justify murder, thus why I think the nazis did the "bad things," to which the response wasn't dragging nazis from their homes, it was all out war against uniformed combatants and the violence was justified. We did however drag many Japanese Americans from their homes during that same war and put them in camps, which I also think was a bad thing.

So what "bad things" justify political violence? To me, basically genocides/pogroms and that's it. To others it may (and does) mean "wrong opinions" but imo Ideological "first strikes" just make you the "bad guy."
