And where do you draw the line?
For example, do you think CSAM should be legal as long as those in the material are fictional?
If you think that is not okay, would it make a difference to you if those in the material were not "realistic" (but still underage)?
I don't think people are suggesting it should be illegal because they personally don't want to see it, but rather because they believe that it is damaging to society as a whole.
