Yes, and it is detrimental to the espoused value of intellectual curiosity. Sincere disagreement is fertile soil for productive discourse. It gives each side an opportunity to test and refine their beliefs and learn from one another. If you suppress one side or the other, no one is forced to be rigorous in their thinking or reexamine their priors. Everyone gets trapped in an intellectual local maximum. The result is threads like this, full of comments nearly identical to each other and devoid of anything interesting.
