Please. Generating so many paragraphs here displaying this sort of smug assurance in your own conclusions about highly controversial topics is the exact opposite of "overcoming bias".

One person doesn't need to pretend that he doesn't grasp something until a certain critical mass of the "right" people catch up. Correctness isn't up for a vote, and the feeling that it is is nothing more than an artifact of social wiring.

You do not have to accept the conclusion. You also do not have to insist that someone else mimic your own uncertainty about any given topic. At the least, perhaps you should go and make sure his reasoning is flawed before you do.
