Amusingly, Mr. Loudmax, you are being far more rude, and therefore deserving of a downvote, than I ever was. I believe the word "permitted" with regard to social sanction (HN votes) has a greater range of meaning than you are permitting here. And even if what you say were true, there is no blind "denialism" in my post either. In fact the sentence in question could have been written by someone on either side of the climate debate. Only a humourless po-faced person, the type on a crusade and using ridiculous words like "denialism", would downvote it.
Questioning of all science is encouraged. Blind denialism is discouraged because it is idiotic, but permitted.
