Actually, I think it's good that mods state their opinions, and clearly at that. As you or, maybe, Crashfrog implied, biases are inevitable and a pretense of objectivity is kind of deceiptful, and purposeless anyhow. The important thing is not to control the thread with those opinions. Authority should only be exercised to ensure decorum and that forum rules are abided.
Incidentally, and as an aside - to help other understand me - I believe in evolution, for sure. Debates on the subject are not of interest to me, though, so i don't participate in them. Faith and I, obviously, share conservative philosophies, a conservative outlook, a great respect for Judaism and Christianity, and a perspective on the evolution (couldn't resist) of western civilization. We share concerns about blatant sexuality lowering the tenor of society, and emotionally and psychologically injuring children developmentally (well, given my career as a child therapist, maybe the latter is more mine). And we share a concern that our civilization, in an effort to be fair and nice and tolerant, is losing a sense of itself, a sense of boundaries, a sense of what is innately meaningful.
But, we have very different attitudes about faith and its practise, something about which we've debated in disagreement at another forum, several times - and which we don't discuss in our occassional private email dialogue..
