I warned a parent bringing her 9 year old that this was a r rated scary movie and she said "Yeah I did my research to make sure there's not weird shit like tits in it but he likes these kinds of movies, hes a freak".
So anyways, murder is fine, tits are not.
If parents can't even effectively protect their children from seeing a R-rated movie, what chance do they have of shielding them from online porn?
