I'd have to suggest no. As much as I love a good political argument, I don't think it has a place on the forum, unless it specificially relates to IT policy. I could imagine such a forum going down-hill very quickly.
It is nice to see a certain level of decorum being maintained on GZ, unlike many of the other forums out there. To introduce a Politics, Religion or other similar forum is just a recipe for the standards maintained on GZ to start sliding downhill.
