> But you're also arguing that he needs to be able to get scarier
No I'm not. The opposite.
If the only tool you know how to use is abuse, then when you need more all you can do is abuse more and more, to the point where you are literally encouraging people to kill themselves.
If you learn other tools you can use them instead when needed and they have an impact.
If I heard Mister Rogers say something was extremely serious I’d stop and listen because he’s a calm and reasonable person. If I heard Linus telling another person to kill themselves I’d think it was him being terrible again but I wouldn’t take notice of what he’s trying to say because he uses that kind of abuse for minor things anyway.

"If", yes.
Is your argument that because he put abuse into emails, that he must not know any of those other tools? I don't think you've justified that argument.
He could use the same tools anyone else could, in those situations.
And you're still saying that he might "need more" in certain situations, and I don't think he does. He doesn't need to instantly catch your attention via acting unusual. Much like Mr. Rogers would do just fine at telling you about something serious if he used his normal voice / normal presenting voice.
He uses personal abuse against people. Not sure that counts as 'threatening'.
Really we should always challenge any kind of abuse.
