Seamus: Easy? Are we reading the same thread? Seriously, not sure if you're referring to the changing or the accepting but I would not call either easy, nor one the same as the other. Artists create, audiences accept… or not… minutes or centuries later.

Social media, folk clubs, friends and families have the luxury of simply voting/shouting down their immoral others. If one's vocation is to study, preserve and present the works in their original forms… ethics and law should trump morality. The upfront disclaimers are there for the suits, yours and theirs and the State's (aka: CYA.)

99.9% - don't care. <0.1% - Yes, no, maybe, what if… any subject, any minute or century.
