Ban words Russ? There are any of myriads effects which are indisputably anthropogenic. climate change I don't know enough about to separate anthropogenic from other factors, but mainstream science seems comfortable discussing them both. Banning words from public discussion can have chilling effects, making that discussion incomplete and less worthwhile. On other topics we seem to allow participants to allege one thing and for others to come along and refute, and we all remain good friends. Would rather that someone cross a political line before we rule speech out. But its not my forum obviously.
