"Allowing?" You sound as if there somehow would be no "shaming" and "bullying" were it NOT "allowed" that a discussion take place.

That's a rather extraordinary claim.

An open avenue for discussion/criticism of a PUBLIC figure must NECESSARILY enable "shaming" and "bullying," along with legitimate scrutiny. You can regard it as an unfortunate "side effect" if you wish, but don't allow yourself to operate under the illusion that all the resentment, unfair criticism, and nasty thoughts will suddenly evaporate from the minds of "haters" once you forcefully muzzle all discussion of someone's publicly-distributed product.
