If there was some semblance of consistency then I would agree with this but sex isnt inherently bad and certainly anyone 12+ should be familiar with sex. Everyone knows they go lie when they go to pornsites and hit the "Yes Im 18". If you are that concerned then a simple age 13+ filter would work. But these "concerned" parents dont give a damn if their kid watches something extremely violent, as if brutal murder and loss of human life isnt immoral but somehow reproductive actions which create life are.
