In direct contradiction to what you say, there are many businesses in red state US who will stop you from wearing a mask if you try to enter.
Or "stop you if you try to enter while wearing a mask"?
Or are you talking about wearing a ski mask inside Idaho Regional Credit Union in July?
Jerks are everywhere. And they exist in blue states too my friend.
I live in a red state and have not seen this anywhere.
In fact my state encourages you to do what you want, including wearing a mask or refusing to do so. Nobody will bother you if you are masked.
