If you set up a movie screen on your front lawn and start playing movies that cause the majority of your neighbors to come over and beat you to a pulp. I would define it as porn.

If you watch the same movies in the privacy of your bedroom, I would define it as your business.

If you set up a movie screen on your front lawn and start playing movies that cause the majority of your neighbors to come over and beat you to a pulp. I would define it as porn.

Say you live in a neighborhood populated by many homosexuals. You put a movie screen up and start playing a video talking about the evils of homosexuality and your neighbors beat you up. Is the video porn?

Say you live in a very conservative neighborhood with many military veterans. You put up a movie screen and start playing a video that call soldiers baby-killers and your neighbors beat you up. Is the video porn?

Your definition doesn't work.
