It's all about what sort of group you're playing with. I run a group for some kids at my school and I know they would be heartbroken if I just straight up killed them.
I've only had to do this once though. I made it a lesson about caution. The player was being reckless, and they 'died'. Seeing how distraught he was, I decided after the encounter, that the other players should roll for a perception check, and noticed the character still breathing slightly. It was nice to see the kid perk up immediately afterwards.
Killing people for drawing comics IS right-wing motivated murder.
And no, its not moving goal posts because it's the example I've been giving this whole time to illustrate the insanity on display.
I did however offer you a slight concession when I said "or were critical".
Here's the thing, you cannot provide examples which are comparable to the insanity being projected by Islamists.
