I spent a few years hanging around the VC-adjacent scene in a major city, met quite a few of them (because I'm that way. elevator docent during events... priceless).

There is publicly performed theater around VCs which is pretty consistent, taught in incubators, etc., etc. So that's how they manage set and setting (grooming) for the marks. Internally there are certain tells, that they must act a certain way. There are arbitrary character tests and whatnot which provoke a "culture" if you will, similarly to how computer languages and tech stacks form distinctive cultures if left unchecked; there could be self-selecting pressures (for these behaviors) as well. This is unsurprising to me as someone who analyzed voting patterns, and was asked numerous times variations on the question "is it something in the water or 'new car smell'?" (I don't have an answer for that question.)

However VCs are much more stovepiped and cliquish concerning their actual selection process than people realize, I've heard it publicly described as "mafia like" by someone who I worked for and whose name many would recognize. I don't understand why this person, like so many others, invested so much effort... enough to get some serious butthurt IMO.

It's a distraction, it effectively destroyed a different company I was working for.
