No, we are not bigots for calling a person who is an anti-AGW for reasons of stupidity, lack of education or research into the facts, lack of years of noticing what is happening, illogical thinking, or other reasons, a "denier", denialist", a "deniglical", a "rabid skeptic" et al.
They are often bigots, however, in accusations of environmentalism as a religion, and other numerous name calling that has really nothing to do with experiencing what is happening in an informed manner. 91*F here at 8,880' in June when old timers in '97 said the highest they had ever seen it was 85*F in the middle of summer. Since '97 it has never been over 82*F here in June. The reason I moved up in altitude was anticipation of worsening AGW, which has happened. The rammed earth tire walls really help keep it cooler in summer. Still, we used the free solar electric fans today. I feel sorry for lowlanders (i.e. below 8,000') who have to pay a high price for AC or suffer with the heat. Played "Born Under A Bad Sign" in the cool Earthship on my solar amped JT134VineFMTSB. AGW progressing to CAGW is a bad sign for the future of our biosphere. Denialists are the enemy who have successfully kept gov't from forcing HGHG emissions reductions since 1997, and the people getting less aware of reality since circa 2007. They, in effect, have killed countless future humans and other species. Murderers who should be red worm composted as their best purpose.
