The question is, do you completely ostracize the immature and potentially abusive people or do you socially shame them but offer them a legitimate path to being able to be in a group? Geek groups are frequently the last resort socially - its way down on the social ladder (at least when I was growing up) and people frequently are way behind on both social skills and tact. As such, they end up being a catch-all, and the last place that they can go to grow without completely removing themselves from society. Should that mean that people should feel safe? Of course - thats why you meet in public, and have other people around. Not defending this person, of course - just offering a wider perspective. I'd certainly pull this person aside frequently - if the group allowed for it constantly rather than shaming the person then I'd immediately look to leave the (now toxic) group if I couldn't convince them of the danger.
