Mmmm all those salty Zoner tears, so tasty. Sorry, couldn't help myself.
It seems like a lot of people have forgotten that this game features antagonists actually played by other human beings (unlike many pen-and-paper roleplay settings) - i.e. you can't treat other players as NPC's that you can ignore or expect to follow your whims or way of reasoning, however pristine this reasoning might be to you, and there is no Game Master to be won over either. To think so is indeed "bad roleplay". And folding the cards and disbanding when coming to this realization is just so tame that words can't describe it - again a case of rather weak RP (or super strong RP if the goal is to roleplay a bunch of hypocritical cowards).
IMO a good "roleplayer" is not necessarily one who spent hours researching and carefully drafting a rich character background etc., but one that is able to respond to conflicts and inputs they did not see coming from other players while staying in-character (something quite a fair bit of Zoners also have trouble doing when they get pirated by someone unfriendly to them - or get stopped in Alpha in a Juggernaut full of Nomad remains - as if the concept of others never using Freeports is unfathomable), just like a real-life human being have to respond to outside inputs on a day-to-day basis, however nasty, unfair or unpredictable these might be. It's life. It should be Zoner life too, I think, if the intention is to maintain the illusion of superior roleplay.
