“”Would this make someone mad? Would this be hurtful? We will have those talks,” she said.”
At first I was gonna’ call this guy some sort of PC wimp. However, since one of the primary jobs of a museum is to educate, they are at least saying the right thing.
If their supporting explanations come across as truly educational, including how pervasive this symbol is historically, some folks might even walk away saying, “That’s really interesting. I had no idea that someone besides Nazi’s used the swastika”.
Given the state of the secondary school system in the US, the museum might well provide that rare “teachable moment”.
If they write their information like a disclaimer, then yes, plenty of folks will reflexively become offended/outraged/troubled/hurt. Lot’s more folks need to “man up”. Just state the facts, and those that have risen above the PC psychosis will have learned something. The rest...may be too far gone to help.
Hopefully, it will educate in the positive way you describe. ;)
