Which has a worse impact on children?

I see that movies with Sex and Sexual content are rated higher than movies with High levels of violence/obsenities

Also; Sex is a natural thing
Violence is in a way natural, but the explosions and guns in movies are definetly not?

Perhaps it's the fact that the violence in movies is mainly computer generated and faked, while sex is real?

Does anyone else have an opinion on this?
Or which has a worse impact on young children, or society/people in general

See the thing is, people still see sex as something that shouldn't been seen, you know?

While violence has just made its way into movies, and is more widely acceptable.
Personally I think it would be worse for a child to see two people fighting, rather then seeing to people make love, which can then be explained to them as a natural, and beautiful thing.

You know?

I agree that people think sex shouldn't be seen
But it should be
America alone has a multi-billion dollar porn industry
People obviously don't mind seeing it...

It's a completly natural thing
Whereas shooting someone in the head isn't
But you can get that on PG
But sex is MA - R

I'd rather have 2 broken legs than an STD.
