Never been kicked from a group; if I make a mistake I own up to it and admit that I messed up, and I think this is the key here. Too many people from my experience will either try and stay willfully ignorant, or when they get called out on it, they get super offensive. Seriously not trying to criticize, just trying to make things run smoother, and you people take it like I've insulted your entire family tree line while subsequently burning your house and all your possessions on your Birthday. I've never seen people get so sensitive before.
