The more I think about it, the more Im surprised this is even being discussed.
I mean seriously, this is first and foremost a MUSIC related forum, why on earth would someone want to bring their possibly controversial views here when there are so many better places to post those things where people go that actually WANT to read stuff like that.
A quick look at some other music related forums reveals that no politcal/social commentary section exists for the ones I saw. Likewise, a quick look at forums that cater to two of my other interests (photography and firearms), reveal that for photography none of the ones I frequent have a politcal/social forum, and for the firearms related websites, revealed that some did and some did not.
As for the issue of moderating, get over it and get used to it. As it has been said before this is a privately owned forum and as such free speech has limits here. There is another website I belong to that performs much more heavy-handed moderating than what goes on here, and I often had posts disappear without any explanation. Eventually I was banned for violation of the forum rules. It was only after that I was banned that I went back and read the rules of that forum, and realized there was a reason for their existence. I was allowed back in eventually, with the promise of complying by the rules of this PRIVATELY owned forum.
My insensitive and heavy-handed advice is that to those who dislike they way that this PRIVATELY run forum is managed, is to either acccept it as one of the many places in life that exist that have rules in place, or to start your own forum.
Peace Out
