I disagree. AGW deniers haven't changed. They have always been stupid. As I've continually pointed out, statistically, AGW deniers have few science & mathematics degrees. Almost all do not have science & mathematics with their poorly earned hi skule DEE-plooomaas & numerous toxic topix AGW deniers have no hi skule DEE-plooomaas.Deniers don't move on, They just get angrier and angrier and dumber and dumbed.
As far as anger, toxic topix AGW deniers often are slimy steenking filthy vile reprobate rooting(& rotting) racist pukey proud pigs & quite a few are savage alleged & proud threateners. One in particular, bob burns, is a human piece of garbage........sorry, you have to eliminate the term,'human'.
