Pornography just is,it exists and it is there and any moral value that we make is just a subjective one.
Porn is just people having sex in front of a camera,sex is not wrong despite what any religion can say so there is nothing wrong with porn.
It is us that make a moral judgement and can decide to watch it or not, pornography on its own is just like the stars in the sky, they are just there and they are not good or bad.
