Let someone yell at their hallucinations or let someone ruin someone else's life using the full force of institutional or corporate power? Pretty easy choice here.

An old schitzo used to frequent my local coffee shop all the time, would be pretty out of it most of the time, never bothered anyone beyond his normally bad attitude (a saint compared to many non-schitzos I know). He was disheveled, rarely without some form of stain on his clothing and he smelled a bit funny, but so do some of my coworkers. Had a good conversation with him once while he was "selling computers" to people (broken graphing calculators he had been collecting from college students) and I was able to break through to him for a few minutes. He claimed to be an old veteran who was on a bunch of helicopter missions back in the day and the experiences he went through pushed him over the edge. All his friends were dead, family had essentially abandoned him, he had no one left to relate to and no means or connections to find a community that did. The moment of clarity only lasted for about 10 minutes before he went back to rambling irritably about the "mess" people were making around him (the place was nearly empty). I would choose that 1000 times over the other group in question.

The weirdest thing was that his "on" conversational voice was totally normal, his entire persona changed the moment he noticed that I wasn't just there to shoo him away or make fun of him. Not one hint of any of the ticks he displayed when he was "off." He was still "in there" but he just would fall back into whatever weird palette of coping mechanisms he had developed over the course of his life to deal with the insane backstory he claimed to have. Therapy probably could have easily helped him but he was like 70 and basically self-reliant even with his ticks. Pretty sure he was just running out the clock at that point. Anecdotal for sure and he might be an exception (or faking it) but it's my only non-medical field exposure to someone who was perceptibly in that state of mind.

I know that there are people in this category who are much worse off and are potentially dangerous, but I can't say that I find any analogue of that spectrum of risk when it comes to the cancel crew. It's either on or off and you pretty much can't risk saying a damn thing around them if they're in the "imma destroy your life" frame of mind.
