That I can accept, but we hear many PvPers call PvMers care-bears, trammies, etc. because they prefer fighting something that has loot while risking little. You see if you're raiding a spawn and you wind up dying, you're not risking dropping anything of value, so does that make the PvPers doing the raids Care-Bear Cousins? You know, a bit wilder, but the same when you really get down to it.
Nope, don't think they are born that way, but all things considered, if so many PvPers enjoy preying on people who have no interest in PvP for enjoyment, to the point they will defend the proverbal carrot on a stick approach for easy pickings, it speaks to a measure of sadism, slight though it may be as this is a game, that not everyone is born with either.
I'd say it doesn't exist there either. No longer is Red a risk, you have full access to all the cities, and Forged Pardon's, and the removal of perma-red have eliminated exclusion from other facets as well at this point.
I've engaged in PvP, not that I particularly enjoy it myself, I've defended spawns from raids, successfully and sometimes not so successfully, and while many wouldn't consider it PvP, sneaking a thief down to steal scroll is a one player (the Thief) pitted against another players defenses and provides it's own challenges. That's not to say I don't enjoy PvP in some other games I've played. SW:TOR's PvP mini-games are quite enjoyable as they reward both sides, though the victors are rewarded more, but that is an entirely different concept.
It's really not exclusive to Felucca anymore, with Scroll binders it's time consuming but there are alternatives to acquiring scrolls yourself. The only factor in this that is exclusive to Felucca is PvPers wanting a baited pit for the under/unequipped (either skill or equipment wise) and/or unprepared.
