Assuming blackface minstrelsy was defacto racism is not history.

Minstrelsy's most successful sub-genre, the Tom Show (Uncle Tom's Cabin,) was abolitionist, lefty, fellow traveller, 'wokism'... in burnt cork blackface.

The medium was Anglo-American entertainment's TV and radio for over a century. You're saying the producers, artists and audiences had no politics of their own, just yours... or you don't care.

Assuming all or no blackface Morris dancers are/is racist are both ways of avoiding thinking. It's easier marketing, but let's not mistake it for good social skills or research practice.
