I never read anywhere that "PvP is bad" on these forums.
People despise and hate griefer/ganker.
Please learn the difference
Fortunately i am the one of not so many here, who do not need to learn that difference.
Many people there is calling other people griefer who are just playing a game.
For example community goals or ruins. You want to haul a fish to win CG, but some other may not want to make this CG complete. Then they are trying to stop You and then You are calling them a griefers.
Some other want to prevent a war between humans and aliens, and preventing tresspassing on a graves of ancient civilisation, but again, crymunity is calling them a griefers.
People are playing a game as they like in a proper way. I will tell more - they are roleplaying, bringing some story and content, instead of crymunity who want iWin button and giving nothing to the Ed universe.
You may not like it, but its a part of the game. It is also not means its wrong. Its only mean you not like it.
Both success and failure are a part of gameplay. If someone is refusing a failure, then he also refusing a success, because a success is folowed by a path of failures.
Unfortunately a "modern educayshun" is not teaching people how to deal with a failure. Society accustomed only to winwinwin and success, and in a case of even smallest failure, even in a computer game, a people can't deal with that feeling and instead of saying 'ok, lets try again, i will try to learn', is kicking the table, pawns and chessboard, and rage quiting to safe environment with panic fear, or ... painting streets with crayons.
