Love it when you make a statement that porn isnt harmful without referencing any studies, and then demand studies for people to prove it is harmful. You are the one who made the original claim that its not harmful, the burden of proof is on you.
Their side isn't the one trying to ban things. If you want to ban something you have to prove it's harmful. If you don't want to ban something you just have to call out that the other side has to prove it's harmful before they can ban it. It's like how you don't have to prove your innocence against a criminal conviction, merely provoke reasonable doubt (in theory).
Err yeah because everything is harmful by default...
> you make a statement that porn isnt harmful
They did not state that porn is not harmful.
> I don't think anyone has demonstrated any actual harms from porn
Why should they need to reference a study to show the veracity of that statement?
