More specifically, it's nice to be polite, which Linus usually is.
Having a strong opinion about code is part of his job. Wording that opinion great every time and never showing any frustration, while working mostly with public, text based, permanently visible communication, is a pretty impossible standard.
You are literally describing parenting, which has an extremely valuable role in society.
On a broader note, I recently had someone quote that classic adage "great minds discuss ideas, average minds discuss events, simple minds discuss people" at me and I just had to push back. Conversing about the behavior of others is how, by design, humans negotiate cultural values, morals and etiquette. That's not something to be sneered at.
Are you using the wrong word?
Parenting is what parents do towards children that are _their own_. Not random people on the Internet...
Haha. Um what?
It's better to be polite of course, but I wouldn't call someone an asshole or a bully because they sometimes fail at that.
That's... That's a hard one to even entertain as being correct..
