Any player seeking a meta-game advantage because he doesn't want to lose is bound to receive hostile feedback, regardless of the game and the community. It amounts to asking for special privileges and stands against fair play.
I don't think the BM community is overly negative in regards to this. If you went to play Risk! with a bunch of people you didn't know all too well, and during the game you almost get obliterated by a certain player who seems intent on removing you completely, and then by some miraculous chance the odds are turned and you are now in a position to wipe him out. If he started whining to the other players that you are a bad player and that you should leave him be, without offering anything in return, would that please you? I don't think anyone in that position would be all too found of that guy. Nor would the others being whined to.
