Have you met any flat earther pilots

I have heard of private pilots being flat earthers, although I have never met one. There are only a few small things you have to acknowledge in the private pilot test that are directly related to the earth being round, such as how winds rotate around high and low pressure zones in the northern hemisphere - the inner circle for the flat earthers, I guess? But has anyone met any flat earther CFIs? regional or major airline pilots? Almost no pilots ever get high enough to perceive the curvature of the earth with the human eye and that seems to be an important point to the flat earth movement.
