Of course there are instances where cancel culture is abused. If enough people pile on someone they disagree with, chances are it'll have an effect. Become a monster when fighting monsters, and all that. Someone being called out for an unpopular tweet or opinion is bunk. Never mind counter-productive, as per J.S. Mill. But ultimately cancel culture is a way to call out those on pedestals. It is a divorcing of talent from character, which seems progressive to me.
Culdesac's misreading of that tweet is not altogether far-fetched, to be fair. Where cancel culture affects the arts, which it may well do, if only because so much of art and culture exists through sponsorship, it becomes dubious. Art shouldn't be confined to the Overton window. That said, let us not pretend that a Yonnie Cruz was cancelled for his offensive video parts.
