I'm not aware of any partiallity from mods/admin - obviously you get contributors that are partial on certain subjects (myself included) because everyone has an opinion but I have always felt that mods /admin are very fair in allowing everyone to have their say only intervening when people are getting personal or out of line
but I have worked in the charity sector pretty much my entire career and i can certainly second the view that charities are allowed to be partial - look at rspb, rspca, green peace,
Badger trust, so forth so fifth loads of charities take a definite stance on green/countryside/wildlife topics and in fact in many cases its their raison d'etre - so i cant see the charity commision being remotely bothereded by this
