Look, there'll always be some people who take things happening to their PCs personally. It's natural in many ways - we get attached to characters, plus nearly all non-MU* games gauge 'success' based on how well your character is doing, right? It's an easy paradigm to adopt.
The question is whether the community is able and willing to not see consequences as defeat and the first step to do that is to have a range of the former. In many MU* so far the impression is given that making the unconventional choice could result in your character being taken from you, and it is very hard to take 'okay, now I have to roll a new alt' as something positive - I can spin it any way I want but if your character gets tele-nuked as the result of RP you won't have much fun with it.
So it's where it starts, with a page or a job working such things out. "Hey, so now that mouthed off to that Pure and publicly humiliated him he'll come back and try to hurt people you care about - got any targets?" gives something to play about. It doesn't close RP venues, it opens them. Sure, your character is now marked but you can do something with it. The objective at that point for both the ST and player is to generate something fun, not flex some sort of ego-muscle.
