I think of course porn objectifies people, we objectify them every day. A person on a page or a TV ad or on TV to some extent is not a person, they are simply a hot piece of *** to hang some bikini, watch or pair of jocks on. They are simply there to promote a product sometimes or to entertain us. Porn is NO different.
Both men AND women are objectified by porn, I don't watch porn to see your average person on tape, I don't think many would. Women want to see good looking guys (or girls) and men want to see good looking girls (or guys) it's just the way it is.
I don't think it's an issue. If you want to talk about objectifying then dont' just point the finger at porn ;)
