The principal is it's OK if a democrat does it. For example: It's OK to rename something named after a Republican president who was shot (Mt Mckinley). It's not OK to rename or change something about a Democratic president who was shot (ie. The Kennedy Center).

Tons of people complained about the renaming of Mt McKinley for the same reason people complain about "Lake America" now. It has nothing to do with the names and everything to do with the reasons for the renaming.

That was reverting a rename. Denali was the original name.
