This is a very dangerous viewpoint in my opinion. There is no true science without free speech. Kepler for example was censored due to his highly controversial views about the sun being at the center of the solar system.

If the science is so shaky as to be blown over by some crackpots then it is no science good at all. Interestingly, some among the flat earthers have independently verified the curvature of the earth. This is a beautiful outcome for these true skeptics and critical thinkers. These are true scientific minds in my opinion.
