Ah, but RAPE is the direct and violent taking of someone's will for the criminals pleasure. Rape victims don't enjoy such behavior. Next thing you'll be saying is gay sex isn't protected either. In their PRIVACY people may do as they wish.
BTW,I draw the line on homosexuality. If they marry, they no longer uphold a social contract. This is why I oppose gay marriage.
People are allowed to smoke, which has more evidence suggesting it being harmful than porno does. (How many people have died from watching a porn?) And you know what? I couldn't careless if people smoke (or even WHAT they smoke for that matter) so long as it doesn't hurt anyone else.
And whats the 4th Amendment if not a means of keeping private habits private anyway? just a question...
