I personally have no use for pictures of baby genitals, but you really do huh? It even makes you upset we want to take away your baby genital pictures huh?
Is this some perverse form of individualism?
Edit: if you took a picture of you cleaning your daughters vagina out, and showed someone, yes that would be child porn and child abuse.
Depends if you are talking legally or morally. I disagree with a lot of whats legal. Your examples are silly and easy to answer:
If they want to be tickled than yes, if not than no. Punishing the child is for their own best interest, not to get them to learn to listen to the king of the house better. We make decisions for them because they aren't capable of making the best decisions for themselves.
So how exactly does taking pictures of them naked when they are babies or children, help them in any way?
Its a stupid tradition. Embarrassing people is always bad. Purposely hurting people is always bad. Regardless of the trauma it causes it would still at best make you an incredibly selfish person.
