They're not deserving of respect, they are social misfits, likely even sociopaths. It's not a political issue in the least, it's an issue of medical science and public opinion vs the rest.
The majority locals in the city wear masks in supermarkets, etc, including the staff. They do it to protect others. not so much themselves as pointed out not long ago in this thread. I may as well return the favor. If it makes one staff member in a supermarket feel more comfortable, it's been a good day.
