So you allow people to have sex on the beach in front of kids and don't say anything ? Then you are just as much the problem. 

We constantly allow kids to be exposed to things their minds can't process and then wonder why we have messed up kids.  Teenagers "choking out" some old 70+ year old woman while he robs her. Teenagers performing drive by shootings.  We "adults" create or allow the situation and environment that poisons the young minds we are supposed to nurture, and then ask "and what is your point" ?  Our own greedy, self righteous, self indulgences are the problem. Then we sue those that caught us and teach our kids to blame everyone else.
