Alright, I grant you, at least half of humanity wouldn't voluntarily wear a mask even to save the lives of their own family, as we've seen time and again. But the purpose of the masks is to save lives, like wearing a seat belt, or not drinking and driving. Sure, most people would rather drink alcohol while driving without a seat belt. But we don't allow it anyway.
That's not dehumanizing. It's the epitome of humanization. It's about civility, compassion, kindness, and overcoming cruel dispositions and rude habits to become or be made more humane.
