Wikipedia has plenty of built-in mechanisms to deal with content disputes, such as request for comment and mediation, and eventually recourse to one or another might have to be seriously considered. I'm sure everyone thinks that every other user has some sort of "behavioral issues", but talking about them on this talk page so far hasn't solved anything. Unless we take IJethroBT's advice, the only remaining solution is to actually follow the rules of Wikipedia, which require that article talk pages include only content discussions and that users seek resolution of content disputes through normal mechanisms including request for comment.
