Is it OK for a 21 year old guy to date a 13 year old girl?

Oh my god, that's disgusting. And you say he's a youth pastor?!?!?! What the heck?! That's the sickest thing I've ever heard. He is definitely misusing his position and you need to tell his superiors at the church, and you should probably call the police as well. What is our world coming to??...
