Wearing a mask in completely about politics in the USA. Most if not all social media posts about people wearing masks have people wearing completely useless fashion items on their faces. I'm sure it is mostly because they don't know better and partly to virtue signal.

In any case there hasn't been any studies related to efficacy of wearing a mask in public to reduce the risk of infection, so not wearing a mask is not as crazy as some people make it out to be.

This all said if I would use public transport I would be wearing a mask (just not a cloth mask or a surgical mask) or if I visited other places which were packed with people, but best solution is to just not go to places which have a lot of people in them.
