If you look at the demographics in the western world, you will find that the split among mask wearers and non-mask wearers is much more profound than simply wearing or not wearing a mask. The two camps are mostly centered around two different world views and the issue of mask wearing has mostly been co-opted as a proxy for those differences. In other words, it is not mask wearing that is dividing us, it is just a manifestation of those underlying differences of opinion.

To put this into perspective, no one is objecting to all the rules surrounding driving a car, for instance, even though the requirements for operating a car legally are not small (you even have to carry around a "passport" to show you are allowed to drive the car and present it upon request to police).
