It seems poorly considered to characterize social pressure as a witch hunt. It is acceptable to encourage others to share your moral convictions, there is a vast gulf between that and a pitchfork mob.
That... doesn't seem true to reality. Maybe I'm remembering it incorrectly.
In my view, society would become severely dysfunctional if we are expected to withhold our negative views of someone's choices, from fear that too many people will share those views.
