Sometimes it's a realization that one just doesn't fit in the forum, for any number of reasons that don't have to involve a flaming exit, but just discontinuation of membership. Doesn't need fanfare. I rage quit a forum before, many years ago. Nowadays, I just take a walk. If it gets too intense in ways I don't like, the internet is big enough a place to set down roots elsewhere. This place is one that has some things I don't like, but nothing that makes me want to leave- just to shake my head. Before anyone asks, it ain't the management. If anyone actually cares, they can try to figure out what I don't like for themselves. At some point a person has to be big enough to ignore some things, to enjoy the remainder.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
