I feel obliged to point out this serious medical article from US News and World Report.
Spanking Raises Chances of Risky, Deviant Sexual Behavior
THURSDAY, Feb. 28 (HealthDay News) — Researchers have uncovered another damaging consequence of spanking: risky sexual behaviors, or even sexual deviancy, when the child grows up.
And, umm, what are the consequences where the person being spanked isn’t a child? 
That’s pretty much saying EVERYONE has deviant sexual behavior. Isn’t EVERYONE spanked as a child?
And on a side note…as an adult I very much like being spanked.
*ahem*
I promise to only use my powers for good.
AHAHAHAHAHAHAHAHA
Oh.
That explains everything, then.
