Our friend Joe S., from the West Side of Cleveland,contacted the 1851 Constitutional Law Group, and asked if there are any violations of constitutional rights if a private security guard, hired by a local store owner, stops you from entering a store because you are not wearing a mask?
Answer from the 1851 Constitutional Group:
None. Private property owners are entitled to make their own rules on their property. Your recourse is to go elsewhere.
[LFC Comment: Makes sense to us. If going to the store wearing a mask bothers you, then you may want to consider using Amazon, and have them deliver the product to your home.]
