Seems like we're describing different people in that case, as I would agree that kind of behavior is unhelpful. That kind of thing isn't synonymous with people who are skeptical about the game, in the same way supporting the game isn't synonymous with ignorance.
Also, people who don't think the game is going to happen =/= people calling the game a scam. Personally, the majority of skeptical community members I've spoken to (and myself) consider it more or less a mishandled project, not something actively malicious.
