I'm sure the founders of the parks (whom all had the same rights we share as Americans) would be happy to know that their freedoms and their history were denounced in the year 2017.
Well, the founder of the park was Angus Wynne, Jr. who is dead, so I don't imagine he cares overmuch. Beyond that, he mostly did the flags thing as a gimmick, and wasn't a Confederate loving yahoo racist, so, again, I don't think he'd care much. As for his rights, he sold the company before he died, so even if this were some sort of rights issue -- and it isn't -- he'd have already turned those rights over to the new owners, who made this decision.
