It's a fun oddity about it - really it is - but doesn't the entire premise already boost it into the M for Mature/15+/17+ bracket regardless of what you see and what you don't?
KS with a sex-less or sexually vague plot (or with sex but also with parental guidance) could land a 12+ or 13+ rating and more than a few "recommended for teens" approvals. (I think it's a bit too deep, and probably would bore, preteens, but that might just be me.)
Even "clean" LSL seems rather cheap, sleazy, and shallow, and not at all conducive to being a good person.
Maybe it's for the best. I could see some people getting rather tensed necks back there./derail
This is a better direction for the thread to take, it seems.
