It's perfectly fine to disagree with someone, but moomba always comes across with this holier-than-thou attitude as if to say that anybody who's trying to make the situation better is some kind of rabble-rouser who should just shut **** up and "do his job." Well, that's not gonna go over real well so he shouldn't be surprised when people think he's a **** and tell him so.
