I guess in your mind hitler isn’t a mass murderer because what he was doing was technically legal under his regime. To each their own if that’s how you want to logically frame your moral logic.
Personally imo, if I create something and that something is MY work of art and what I put my own blood sweat and tears into, and I want it to be inconvenient to watch because that’s my prerogative, that doesn’t give you the fucking right to watch it. I don’t want someone like you watching it.
