>But showing them violence is OK?

Well, let's put it this way.  If you show your children an animated 
Japanese pop star in a simulated rape scene you're asking to get into 
trouble from the law.  Someone will call Child Protective services or the 
local authorities.

You show your kids Rambo: First Blood there will probably not be any 
consequences.

Violence is plentiful to youngsters.  Sex and pornography is less 
available.  Sell violent videos to youngsters and you won't get in 
trouble.  Sell sex videos to youngsters and you will get into trouble.

In general, mixing sex videos, books, magazines with minor is a bad thing 
in the USA.

I wouldn't mind a minor seeing a love scene, provided they were 14-17, but 
a person of that age seeing explicit sex and pornography is a no no.
