Masturbating is an action, too. What’s the qualitative difference between a private image in one’s head and one on a screen?
You seem to struggle with separating a philosophical conversation from whatever icks you. If it assuages your sensibilities I don’t engage in this activity, but only because it’s not arousing to me in any way. I just can’t see any actual difference between a fake image in your head and an equally private image on a screen.
When an image becomes public or harassing I think there is a clear problem. If you want to disagree on where the line is between an image in your head and one used to harm someone, that’s fine. Neither of us is drafting a law here so it’s all just wind and words. Have a good day.
