Personally, I think the two factions won't be reconciled because of fundamental differences in what they perceive the purpose of the game to be (or, to put it another way,
why they play the game.) The discourses surrounding the two outlooks are different at a basic level.
That said, I feel that PVP ganking in starter systems, for example, should basically be a capital crime, regardless of jurisdiction. Perhaps the response could be based on the differential between the two ships and the regularity with which the CMDR engages in such behaviour. For instance, someone hanging around Cleve Dock in Eravate in an FdL shooting up some number of newbie startwinders should expect automated, swift and lethal retribution from station defenses when they try to dock
anywhere - there's no place in any game for that kind of behaviour, in my opinion. If, however, the same player were to do it in a starter sidey themselves, the response might be more muted.
Alternatively, every time the offending player started in open, they could be automatically referred to CQC. That would at least ensure a fair fight with players expecting to be shot at for no reason other than that they were there.

(I'm only half-joking.)
