They’re not “dumb as a box of hammers,” there isn’t a single promotor of ‘Global Warming’ that doesn’t know that it is pure bunk, but what else do they have?
This is the last straw for their global socialist agenda, so they’re going down fighting.
I think there’s two contingents. The “scientists” and politicians are as you describe. But take these journalists for example. They’ve been trained (not educated) to believe in science and government, especially on an issue where it seems MORE government power is the answer. So there is a “sincere but stupid” group. Not that the gullibility would be unavoidable if they were to be open-minded, as I pointed out in the other post. But while they still bear the responsibility for their own ignorance, they are at least sincere.
