Should porn be illegal if prostitution is illegal?   stance: porn is justifiably legal:
You can't (at least in America) legally tell other people what they can and can't read, write, or listen to as long as it does not directly harm others. For example, if you are reading, writing, or listening to a direct order to kill someone innocent, and intend to follow that order, it's illegal. You certainly have no right to tell people what they view in their own homes, away from you and impressionable minds in society. Viewing porn in private is and should be legal.
