I don't believe that anyone should be forced to wear a mask. It is your life and you alone should decide what is best for you.
I do, however, believe that a business owner has the right to require masks to enter their business. If you want to enter that business you should comply with the wishes of that owner. If you don’t like the rule, simply walk on by, and find a business more to your liking.
We’ve all seen it on the news. When confronted by a store employee, the anti-maskers say the virus is a hoax, then demand loudly and profanely that everyone else convert, by threat of violence, to their way of thinking. The reason that businesses won't enforce their mask rule is the very real threat of violence by anti-maskers. In the past few months we've seen store employees berated, threatened, assaulted and even murdered. There is a word for this type of behavior. It is quite simply, terrorism.
The U.S. Department of Defense defines terrorism as follows: The calculated use of unlawful violence or threat of unlawful violence to instill fear; intended to coerce or to intimidate governments or societies in the pursuit of goals that are generally political, religious, or ideological.
