(edited) Meh it isn't needed after all. /regrets starting this thread
If someone wonders I was thinking of an unmoderated sub-forum, where all religious, political etc. debates could be moved and they could go on unhindered there, but then they would still show in active topics and clutter the on-topic threads there.
Besides I understand it's better to not start / engage in such threads in the first place instead of overburdening moderators. *self-righteousness abounds*
