OK, let's say that I have an eighteen year old daughter. And let's say that you talk her into letting you take pictures of her in the nude. I don't approve of this and tell you to knock it off. You say screw you and post these pictures on the internet.
I rally support in congress to pass a law saying that to post nude pictures of anyone under the age of 21 on the internet is a felony.
Am I imposing morals on you?
If shes an adult and if she consented to the pics being posted( im an honorable guy and would not do something like this without consent) then you would not be within your rights IMHO.
