I did it... when I went to that horrid group targeted at people with an eating and sugar addiction. It was awful, but I think those support groups are the reflection of whoever organized them, and set some really low behavioral standards! The founders then let their members express in certain way, then more people come, see that and think it's ok, then they start doing it as well. I hated that place, the people there were so incisive and mean, they threw nasty indirect at each other when they stepped to the front and started to talk. I never felt so uncomfortable in my life.
