Too long for comment...
vgv8 has all the hallmarks of someone completely self-taught, and proud of it. Unfortunately for him, his knowledge is full of holes and misunderstandings and he doesn't have the personality to weather the process of having those hammered out of him without some indignation on his part. Okay, a lot of indignation.
In another life I have had to deal with people going through the unlearn/relearn process. It is hard, and when people who have ego invested in the fact that they know their stuff get told that they don't know jack they get defensive. When told they don't know jack in a way they perceive as demeaning, they get very defensive; very defensive people either clam up until they stop getting yelled at or return fire. Vgv8 chose to return fire rather than clam up.
I've dealt with that kind of person before, just not in a technical learning context. What I've found to work best is to take them aside and have a long talk. If you seem like you're actually coming to hear their side rather than the Official Voice Of Orthodoxy to Smite The Unbeliever, they'll vent like a volcano about the injustice they've experienced. This is likely to include unkind language. Once you've gotten through that process and they've calmed down a bit, you can start working on the core of the problem: they don't know that they don't know jack.
Start with a single concept and dig into it. Find out how they think it works and how they came to that conclusion. Then explain how it really works, and why that's the case. There may be defensiveness. You may have to gently invalidate their sources, or explain how their deductive methodology was fundamentally flawed. Repeat for a few more concepts and you stand a good chance of convincing them that they really don't know jack, and that sticking around is actually a good idea if they want to change that.
This is an intensive one on one process that involves a very deep understanding of the topic at hand on the part of the person doing the taking-aside.
The entire StackExchange framework is designed around breaking the very process that can reform users like vgv8. Intensive one-on-one interactivity is exactly the kind of thing that StackExchange is NOT. It is Q/AAAA, not Q/AAA/Q/AA/Q/A/Q/AA.
The taking-aside process is something that can only be done by full up Moderators, and vgv8 is already convinced that the mods are biased against him. The one thing I know of that can cause true behavioral change can not be done because of how the site works. All we are left with is to ban him into the corner until he learns that shutting up in the face of injustice is wiser than railing against it. This is, shall we say, very unlikely with his kind of personality and we're much more likely to get one of two outcomes:
- He will go away, never to trouble us again.
- He will stick around, just to annoy the snot out everyone as vengeance, complete with sock-puppets to get around bans.
The environment where I faced this kind of thing before did not employ community-sourcing for its administration, which actually made it easier to handle. Here any 3K user can vote to close, and practically everyone can downvote or flag-for-attention, which means that if 'the mods' decide to attempt to reintegrate him into the community the community can vote to have none of it.
Which they seem to have done. When October 13th rolls around some of the userbase heat may have waned, but it will take very little effort on his part to rekindle anti-vgv8 sentiment and he'll get banned again. Considering what I've seen of this user, it may be kinder to put him out of our mutual misery and perma-ban him.
