And most state judges. A store owner, manager, etc., would be facing personal civil rights violation suits for forcing the issue. Its happened already. Most wise ones dont push the case. They may have the power to do it, but they dont have the right to do so. Its discriminatory and they will get rolled up and squashed.
A retail store has been ruled a place of public accommodation for this purpose, they are not private. They cannot discriminate due to disabilities. They cannot pick and choose their customers based on whims of their own choosing. . . Even health department mask mandates when there are exemptions in the law, and every state has such exemptions for those who are medically unable to wear masks.
Store owners, Mayors, city councils, health departments, homeowners and condo associations, and police cannot ignore the law to impose their lessor authority to prohibit people who are medically disabled from having access that non-disables people can access without being wrung out to dry for abusing the rights of their abusee.
Property rights do not trump all things. There are reasonable use restrictions especially when they are open to the public.
Thank you for your reasoned and polite response. We might not agree, but I appreciate your input.
(And yes, you very well might be right from a legal point of view.)
