The only people I've ever heard use the words "settled science" are Republicans. I wonder why?
Likely brain infarction? Oddly enough, as a person who READS and REMEMBERS, I've seen the term "settled science" used a hundred times here, and in every case, it was by a Lefty quoting the preponderance of scientists that all agree.
But then what does that really prove? When you become a Lefty, you agree to agree to agree on everything, walking in lockstep with all your mental masters. And if you DON'T agree, then you just don't get hired. It's how progressives survive and spread.
At one time 100% of Europeans all agreed that the world was flat too and that your ship would sail off the edge. So much on agreement. That too was "settled science."
