And, I'd add, gives to them specifically to be dismissive and to imply that the out group is failing to (or maybe isn't able to) understand things with the special insight the in-group has.
Insults are in the ears of the beholder. A bit of context goes a long way, when you realize that that the "in-group" is miniscule, and the the "out-group" is the vast majority.
If you frame it that way, it should be obvious that the "in-group" in this case would appear, on the surface, to be a bunch of deluded eccentrics, hardly anything to feel insulted about.
If the title had been "Urbit Is Not for Normies: How Urbit Will Save the Elect from Eternal September" I would agree.
As it stands, the intent here seems to be to disarm the reader's own insecurities about how whether they are able to (or welcome to) grasp what the Urbit project is about.
