18 is just some arbitrary number chosen by the government which idiots like yourself mistake for some number 'chosen by God'. I've seen full blown HB10 14, 15, 16 year old hotties before so obviously nature didn't intend for '18' to be some magical number where showing sex with girls of that age becomes 'ok'. I would rather watch a hot 14 year old getting boned in porn than some 30 year old past-her-prime saggy titted 'MILF'. And I'd rather have sex with the 14 year old IRL too, does that make me a child molester because I breached the magical number given by the law?
Animals on the other hand I would definitely not have sex with but as I said if some guy or girl down the street gets off over that and wants to watch it or even have sex with his/her own dog or whatever then I have no problem with that and it is none of my (or your) business really.
Stop trying to push your morals onto others especially when you are severely lacking in logic and haven't even revised your own morals thoroughly.
