The reason Moderators generally hold back on opinions or don't get involved in arguments is to avoid people thinking they are biased one way or the other. I'm generally moderate on most political issues, but when I was coordinator in the Den, I was variously accused of being a bleeding-heart liberal, a "Busheep", a "fundie", I was accused of being biased both for and against Christianity, so I figure it's better to just hold back and avoid all the hassle.
