This man was already expelled from high school for selling porn, so he’s had what amounts to an addiction for a long time. No Class Reunion invites for him. I cannot even imagine how my family would have felt if I had disgraced them in such a low and shabby manner.
Now, he has burned his bridges AGAIN by acting to sue his elderly parents who don’t have money or even a lot of time to waste on this kind of nonsense. He should have put them into a rental space. When you move back home, even just for a visit, you become seen as “The Child” again, with house rules for the children. That, I have experienced, but I wasn’t really bothered by it.
I would suspect these movies have lost a great deal of market value anyway. Porn is not rare or difficult to acquire nowadays. He’s a Brat, a Louse and a Loser!
I think the principle here is "As for me and my house, we will serve the Lord" (Joshua 24:15). The rules would apply to anyone, whether related or not, living in or visiting.
