If you really want to talk arranger such as G70, go to the General Arranger section. This is the BAR which I think you can just talk about anything you want to your fellow musicians, let out steam, vent, whatever. I think the real requirement is that you have to be a REAL musician otherwise I won't talk to you (wasting my time)....just kidding there.

About your point on those violence committed on behalf of religion: well, lets say Jesus definitely did not teach those things. He asked us to love our enemies instead. Even when He was about to be captured, He stopped His disciples from committing violence and even healed His captor's injury. As is sometimes happened, people misunderstood/misinterpret these things. But the fact is there are some kind of STRONG proven facts that God does exist. And I suspect those people that says "there's got to be scientific explanations" will probably keep saying those things even when they are boiling away in hell for eternity.
