Pretty sad when people can say that the science is settled just to shut everyone who disagrees up. If you were some kind of expert you would welcome a debate to bash and prove beyond all doubt that the opposition was wrong. And if you run from debate you are simply proving that your position is untenable. Do you know what kind of places had NO debate… Nazi Germany and Soviet Russia to name 2. The positions that those governments took was undefendable BS that was based non on truth but lies.
