@congruent saidThere is an alternative explanation, you know. Cliff may be, like @metalbrain, a troll, who does not believe the rubbish he posts. He posts misinformation deliberately, to sow doubt and discord among others. I'll add him to my DNR list.
I thought Cliff's IQ was at least 80 but I'm not surprised, a lot of right-wing thugs have low IQ (and often have criminal records).
