I guess I could have been clearer on the connection between the original comment and my reply. In my opinion, the "direct attack on human dignity" comes when someone starts projecting the depressing mindset I described outward. To continue the analogy, it's not just being satisfied with internet porn for yourself, it's telling someone else "you don't need an intimate relationship because you can always access internet porn" and I think it's fair to categorize that as a "direct attack on their human dignity".
