Just took a look back at logs of an old incident in FreeNode ##chat where I was kicked and banned for discussing politics while others weren't. Worse, my ban was kept until I agreed not to discuss politics even if others were. Today, I went in there and they have clearly labeled the channel a "POLITICS-FREE ZONE" which at least is fair and honestly, is all I ever asked for. (I didn't stick around long enough to see how evenly that policy was enforced.)
