One is not held in contempt for ignorance; one is held in contempt for choosing ignorance.
We know what you know, and we disagree. It is hard to disagree with a proven fact, however understandable to disagree with someone's theory. Theories are only interpretations of the facts, even if the theory is tauted by conventional wisdom.
If science were as pristine as the method comports, much of our disagreement would dissipate. Unfortunately, we have a large group of people who continue selling theory, as fact, every chance that they get, and many of them find the agenda so compelling they have systematically distorted the data. Humility is hard to find amongst the evo crowd. Telling.
Thought Police dispense with the idea of persuasion.
