The more people who are convinced to wear a mask, the more often your rare scenario will happen. I don'l like coersion, but I'm ok if it leads to a backlash. But I would suggest that everyone who can should wear a mask for now. I recommend the bluish disposable masks although that is based on breathability not efficacy. I have no idea how effective they are.
They are not effective and lead to a false sense of security and excessive smugness. Why would you recommend people submit like sheep to an ineffective tyrannical order? Particularly if you don’t believe they help either?
Actually my “favorite” or least objectionable mask is a simple red handkerchief worn as a bandanna. Heck, I’ve been wearing those riding to protect my neck some since way before covid. Besides, I’m out west, it fits the image. Ok, sure. Wearing a bandanna walking into a Walmart for batteries may not be the same as swaggering into a saloon in the late 1800s and ordering whiskey all around but... You do what you can with what you’ve got.
