Why are we giving this guy publicity? He is the definition of lunatic fringe that I don't want to be associated with.
I don't like wearing a mask and believe they are mostly useless (not looking to debate in this thread, just setting up my point), however I believe that any private business can make any rule or policy that they want (as long as it isn't discriminatory). It does not impinge on my freedom if I am required to wear a mask to enter a park or resort at WDW. I am free to not go to WDW if I don't want to wear one.
If Disney wanted to implement a dress code that everybody must wear a Mickey Mouse T-shirt to enter a park, they have every right to enforce it and people would have every right not to enter if they don't want to purchase a Mickey Mouse T-shirt.
