Policy is not law. Businesses can set a policy, and if you don't follow it, they can ask you to leave, and have you charged with trespassing if you refuse (in most states). But just because they come up with some policy doesn't make it a law. "Mask required for entry" is the new rainbow flag, black square, woke virtue signal calculation by businesses thinking they will lose more customers by NOT having that sign up than the other way around.

It's up to us to prove to them that they will, in fact, lose more customers by requiring masks. This is a difficult metric to measure in states that still have strict restrictions on being out in public/store openings/etc. I think most states are in a holding pattern until a vaccine is available, at which point they will start to lift all these crazy capacity restrictions on businesses. Until then, I will continue to be the only guy in Kroger or Home Depot walking around without a mask and smiling at everyone I make eye contact with.
