To be fair, Seriphyn does make sense. As far as PF and CCPs portrayal of things go, the way the Nation supporters are more welcomed and coddled all over the cluster than others fly straight in the face of what CCP has provided.
It's back to convenience, I feel. It's just convenient to completely disregard realism and invent far-fetched reasons for not having anyone pay the price/face the consequences of their actions. It's honestly very sad to see this go this way, because this philosophy makes almost all RP gravitate into tiny private areas where people can avoid rubbing shoulders with deadly enemies or into a very few large public venues where everyone rubs shoulders with everyone without even a hint of the inter-faction hostility at play.
Those who don't feel like hammering at the fourth wall with a sledgehammer just to get RP - any RP, with anyone or anything, no questions asked - thus get pretty much blocked from getting any RP since it's just easier to disregard realism and consequences.
I'm wholly convinced that there'd be a far more vibrant and wide-spread RP, across more themes and more stories, with more meaningful interaction if this policy of 'we don't care about what you've done, just come play in our channels!' wasn't there. It'd mean people would create more RP elsewhere, instead of just hitching onto the same old drinkin' in the same old bars. More RP locations, and the choices between some shoulder-rubbing and some more faction specific RP without the automatic intrusion of deadly enemies in it.
There's a tangent here about how this philosophy also kills off some of the less neutral RP by creating these black holes where no non-neutral RP can escape from, but that's another topic altogether.
