Pornography is widely regarded as harmless. It's practically impossible to prove that any individual has been 'corrupted' or whatever by reading or viewing 'porn'. (Obviously, in the case of images and so on, this is based on the assumption that the models, actors and participants are consenting adults). I for one think that pornography is harmful. If you start looking at it, it is very hard to stop.
