Offering productive suggestions is not the same as telling people their approach is invalid.
Except little in the way of productive solutions was offered in the OP. That came later in the thread. The OP was about asking people to stop being so brutal in their rejection of RP they don't like. Hambone has a point.
On a side note, I have a thought that as friendly and fair as the moderation is on Backstage, I think it's a mistake to try being so 'friendly and fair' in EVE RP, even OOC. EVE never was a nice place, and I think it's a mistake to promote the sense of camaraderie and 'live-and-let-live' in a game where it is completely legitimate and encouraged to betray and stab someone in the back OOC.
I prefer it when people are nice to me. I want people to respect me, and I want people to respect my RP. I agree with what you're saying, Cas, and I don't like how brutal things are sometimes. HOWEVER, I think it's a mistake to set a stage for people to let their guard down and naturally trust everyone else.
Take Istvaan for example. He's a nice guy, and he's quite polite IC and OOC. However, the very real threat of him completely screwing over your character, corp, and time spent in EVE is real and with precedent. People need to remember that and keep that in mind. Not just about him, but about everyone. A few 'urdoinitrong' arguments and curbstomping here and there helps to remind people of this.
EVE isn't nice, and I don't think promoting Backstage moderation ideals in EVE is what should be done.
