I voted yes for a seperate grouping but it doesn't really matter to me personally, since there aren't all that many politically charged debates happening. The odd 1 or 2 shows up in the Green Room group the odd time which usually attracts attention from the same 4-8 people. Flaming is pretty hard to avoid as people's 'feelings' get ruffled and tempers, scarcasm & whatever else start to run rampant... which is to be expected I guess.
As for no 'personal flaming' towards others, what's the difference between this and 'flaming' someone's country, government or someone's favorite choice in software etc... because a 'personal attack' can be defended by the offended person & the 'flaming' software, country's policies etc, cannot be defended by their authors or officials? Obvious, excessive, over-the-top flaming could be disputed bye certain individuals as their tolerance levels for such may be different for each individual that reads the posts in such a group. It'd be hard to moderate such a group without deterring people from posting due the strict guidelines of the site.
At the same time it is also interesting to see people's view points on global matters. IF it could be kept "civilized" (again, this term is subject to dispute), it would be a good idea.
If such a grouping passes the vote and the admins start one, then great. If it doesn't then I'm there are some people here that have their own forums for people to discuss global matters... I for one wouldn't mind discussion about global matters on my forums.
