I also have avoided them entirely, but there's a long list of stores that has done this and I only read about it in an article tonight. The funny thing is I warned people on Nextdoor a week ago that trying to control people would blow up in their face and to consider if it was worth it.

So apparently the most any employee will do is call the manager. Even if their name is not Karen. They expect it to turn violent. We can use this to our advantage without crossing the line of battery or even assault. Or we could just say something about medical exclusion or religious objection I suppose. But the culturally effective thing to do is reverse the intimidation in all forms; cancel culture, blm, masks, etc.
