No one is destroying or censoring older artwork. This is from a go forward perspective.How is this going to generate actual good things happening, versus the destruction or censorship of old material?
I'm actually not a fan of the cheesecake/beefcake for religious and modesty reasons.... but if you want to cancel beefcake and cheesecake, you will have to go back a few hundred years to some of the best artists of all history and start putting clothes on their work. Artists like to show muscles and curves as a way of displaying their mastery of their art, or something like that. It's certainly harder to draw a barbarian (either gender) with 20d6 individual muscles on display than it is a person in featureless plate armor.
Also, as an artist myself over the past 40 years, it is not significantly harder to draw anatomy than armor. Both are as low detailed as you want, and both can be very complex if you want. It’s preference. No artist I know insists on drawing anatomy as a way to display their mastery unless their specialty as an artist is anatomy. What an odd thing to say.
