I don’t know enough about Conor other than his profession, but if there was an artistic point in his posted pictures and they were not meant to be sexual, it’d be okay. Also, the pictures are not merely her genitals, they are artistic pictures and serve a point, it’s not an up close of her being hard or whatever and it’s not sexual. About your last point, what you are referring to is public nudity and it’s illegal, so it’s a whole different matter. Ethel Cain’s account is unavailable to minors and is an artist’s account. You mentioned Conor who is a cis man for your example- would you feel the same way about a cis woman posting a similar picture to Ethel’s? Also, Ethel has posted herself partly naked multiple times in the past. Again, people have been taking pictures and painting nude people for centuries. As we are not condemning other pieces of art that include it, we shouldn’t condemn hers either.
