I think that this has to come from both directions:

1. Remember those silly class codes of conduct we had to do at the beginning of each school year? Bring something like that back at the beginning of each conference. OK, not quite that cheesy, but a reminder at the start about the code of conduct. Offer refunds at that point if people don't agree with them. Hell, we have to sit through the Health and Safety stuff anyway so it's a good time to add them in. (Speaking of which, I think it's too late to do anything int regards to the guy this year).

2. At a grass roots level. I know it's a horrible analogy, but I remember when I was taking my dog through dog obedience (OK, puppy kindy) that if you don't punish a dog within four seconds for something they've done wrong, you might as well forget it as they will have. In that respect, I think any social reactions have to be swift and to the point. Walk away from a group if something is unacceptable, or very quickly say something along the lines of 'that crossed the line and isn't cool'.
