I suppose the Left thinks they are 'progressive' because they are not calling for burning people at the stake. ;-)
One can look at their rant and sense desperation. Their arguments must be so very fragile they fly into a rage if one questions the orthodoxy.
There is no group so rigid in their thinking as those scientists following the current consensus. They have their grants to look out for!
Considering they are calling for war-crime type tribunals for these 'crimes', I would think execution would not be out of the question.
