It's a cult. The cult tells the uneducated that they're gifted, special and better than all the rest, a feeling they've perhaps wanted to feel all their lives. For them, shouting 'educate yourself' to others is the ultimate thrill because they were never good enough academically to be the professional people they are emulating.
Reminds me of the Melanesian cargo cults but in this case they're cosplaying as lawyers, medics, biologists, etc.
