"you can't tell me terrorism is good because it's never good"

Liberals are so obsessed with something being "good" or "bad" (meaning things that make them feel good or bad) that they miss the point. They can literally acknowledge how slaves killing their masters is effectively self-inflicted by the masters, and the only reason they don't always immediately turn around and say "but killing is bad" is because it was long ago and they're fully aware of how racist they would sound if they did.

"Terrorism is never good" is childish, because "terrorism" is before anything else an insult pointed at non-white people who defend their rights and tactics that many consider "terrorism" (guerilla tactics, surprise attacks, etc.) can be a means to a good end - in this case halting the settlement of Palestinian land.

Adult settlers who voluntarily live in illegal Israeli settlements have participated in a genocide of the Palestinian people, the same way German settlers during WW2 were participants in the genocide of the people of Eastern European nations, and those who took the property of Jews were direct participants in the Shoah. They're not unaware of what happened to give them that land. Often they personally committed the violence. They were comfortable with this because they believed that the IDF would protect them. It's absolutely ridiculous to see people all around the world, who have stood by and done nothing about this for generations as the Palestinians were repeatedly murdered for attempting peaceful resistance, suddenly start crying "terrorism" when Hamas (a group which would likely not exist and hold power without having been funded by Israel) has inflicted violence on the settlers in turn.
