I didn’t ignore it, I called it a straw man. That’s the entire point of my comment.

The argument you are calling “centrist” is not claiming there is a “truth somewhere in the middle”. It’s claiming there are plausible positions (concentrations of probability in your metaphor) in more than just two locations.

I also considered adding that the assumption of a one-dimensional parameter space is also overly reductionist and not representative of the majority of positions people take when they feel like the mainstream choices are both wrong.
