I guess it's about maturity. You have trouble with the immaturity of some other users (understandable), but they act in such a way in response to your immaturity (I'm not saying it's justified, but when you're being treated differently to others, perhaps there's something you need to work on).

Should you stay or should you go? The immature thing to do would be to leave despite the helpfulness of the forum and many of the users here.

I find that this community is really important and helpful. Do they treat me better than some of them treat you? Maybe. But perhaps somewhere in your 2000 posts in one year (wow) you earned a bit of a reputation, and still miss some bits of this community's "forum culture".
