Don't take it in an offensive way, but why does this bother you so much?

If you do your research on reliable stuff you'll see by yourself that people change and their coping mechanisms change too. You may never stop being an avoidant, but you learn to manage here and there, it isn't efortless, but it's possible. Maturity comes for all.

Reality is that you don't know the people on that thread and they don't know you. When you state they are deliberately "shutting off" their MI, you're assuming it's isn't hard for them to write a thread looking for friends. Don't presume you know other people's life, specially when all you know about them is a fake alias and an avatar image picked up by who knows what reasons. You don't know other people's struggles, don't judge them like that. Respect other's coping mechanisms.

People pretending to be avoidants won't make you more or less of an avoidant, you know.
