Oh for sure. I'm admittedly several orders of magnitude too conservative in the simple case. I'll be honest, I expect that to be several orders of magnitude conservative to reality, as you point out.

It's exactly why I'm telling people they are being crazy in this thread. Because people are still defending the "Free Palestine, F Israel" device name as if it's a threat. The supposed threat there is that this starts a fight on the plane. To which the obvious answer is to arrest the person that gets so irritated by a trivial to ignore protest that they decide to start a fight on a plane. Arresting the person making the tacky protest is crazy. The logic people are arguing for is "arrest an annoying person because their annoyance might cause a crazy person to act crazy". Why isn't the answer "arrest the crazy person?" This whole thread is batshit levels of insane
