Shermer is such a disingenuous scumbag.
When you finally corner him, he will either 1.) discount your data as "not accepted by Academia in general", and thus invalid, or 2.) plead ignorance and claim he can't believe your data because he's not an expert in that field.
Keep in mind you are dealing with a
rapist who has no moral principles, and will thus say
anything, regardless of whether he actually believes what he is saying or not.
