I've had a PM on this, but wanted to comment: I don't personally think it's the commenting by others that triggers me, it's the lecturing - especially that I need to be more understanding of an addict, or "get the joke." I like hearing from all sides of every issue. I don't like being told my feelings regarding my experience with an addict are off base.
I thought about this some more today and I also realized that AH used to correct my (and everyone else's) grammar and use of words, too.
This has been important for me - to see how deep the damage went and how much work I still need to do.
