I think you unintentionally abused your daughter by creating child porn of her.
Without the intent of pedophilia you could just be ignorant, but since you are defending it actively, this makes you stupid.
You are willfully ignorant, which is what I mean when I call people stupid or an idiot.
If you really want to insist that number 1 there equals an incestuous relationship then sure I'll bite the bullet on that one. I just don't think its relevant because neither of you knew it at the time nor intended the situation to be incestuous. It was accidentally incestuous maybe, but that's entirely your fault because you are the adult.
Essentially, you were ignorant then and now your an idiot, but it was wrong the whole time.
