Alex, someone just commented repeatedly on one of my articles with denial of the Native American genocide and what I can only describe as 1940s or 1950s children's book descriptions of Buffalo Bill Cody, who did employ Sitting Bull - but he was not around when Buffalo Bill and 150 others, mostly women and children, were massacred at Wounded Knee by US Army soldiers. We have climate change deniers, and we have those who state the US is the "freest" nation on Earth despite ample evidence of rampant inequity - all of which they deny. This would presumably be the new "conservative" commentators hired by NYT. It's a mess. Thanks for a very thorough overview. Denning's a real winner. Yeah, like that.
