I remember when I got here. I didn't feel comfortable doing or saying a lot of milder things, because it was your website, and I was just visiting.
I do wonder what kind of person is introduced to a home, and starts immediately critiquing it based on the standards of a flawed, disastrous modern ideology, and how much of a blank slate they are.
Not everyone has as good manners as you do. Naivete runs deep in certain circles and often manifests itself in very annoying and rude ways.
Some rando internet person who hears that this is the free speech capital of the internet might assume that means cart blanche to be critical right off the bat, without realizing that it should be earned first. And they might just do that. Or they might just be jonesing to antagonize.
You won't know which is which until you give them a chance, and you lose the opportunity to educate a potentially productive user if you don't.
There are several users around here who started off on the wrong foot because they didn't know any better. They wouldn't be around now if they'd been cut off without given an opportunity to hear what was their error and what they can do to fix it. Similarly, there are others who should have been permed far sooner than they eventually were.
There was a point in time in the past where a certain mod would post a rule in a thread with the ultimatum that every violation after that post results in a ban. Naturally, those ignorant of the rule would find themselves banned and have no idea why.
What that user did could be interpreted as being against the TOS but it wasn't explicitly so. With that in mind, I don't think that the first offence of "obnoxious tone policing and shit talking" should necessarily be worthy of a perm. More like a temp ban and warning with advice on how to be a better culture fit. Second offence? Purge their asses.
That being said, I don't see all the numbers that

does and if it's not worth the trouble because of overwhelming odds that they won't come around, or because it's such a big time sink and that time could be better spent elsewhere, then it's completely reasonable to have that policy.
