So in a PG-13 movie, someone can walk into a room and kill a bunch of people. As long as not too much blood is shown, it's fine. If two people have love, it'll be rated R.
... so which is more appropriate in real life?
Not to mention it's kinda dumb that content showing love (or just research) is purely 18+, but you can legally have love once your 16.
So apparently, 16-17 year olds can have love, but they can't look at it. Right.
