Awesome role model ya got there.
Though I gotta say I've dated a girl or two who ended up keeping their mouth shut because of the "evidence of their anti-angel persona acts" I had.
I never threatened any of them with it, and I never would. It was just the same thing every time, they'd say or ask "Will you delete those pictures or videos?" and I'd say "No, but don't worry, they'll never see the light of day again.".
It's kept more than one unruly ex on her toes enough to just move on and not drag me throught the mud out of spite.
If your Dad does it though it will prove nothing other than he's a douche though.
