Exactly. So any one person doesn't get to decide anything. The people who show they can do the content tend to be the ones with authority, for the sole reason that their knowledge gives them an edge on the fight. So if you're useless and get carried through something, you contributed nothing. You have even less of a say than anyone else, because you've proven you don't know what you're talking about. As others have said, if you want a group that won't follow this entirely legitimate practice, make one yourself.
