State run schools and buildings can pass rules like this. They can be challenged in court, in which the arguments for and against can be discussed. Should they be forced to allow a KKK group?
Huckabee Sanders did something similar. She banned the use of certain "woke" words in official "government communications". It doesn't mean people can't use the words in the halls of government - or shopping at wal-mart or posting on facebook.
There is a solid and clear line between stuff like this and a dictatorship, though at first glance they appear similar. For starters, you can vote against these people every four years. If these rules spill into the general public, and you can not vote these folks out, that's when you can start talking about dictatorship, IMO.
