Censorship

I get the reason and the need for censorship on regular t.v. realy i do. Even on the radio especialy the pop stations which are usualy the kids first segway into music. be able to hear a c.d. or play a game until you are 18 i believe is a little extreme if you can't comprehend something is fantasy by say 16 even 14 then you don't have a firm grip on reality and wont have one at 18 either. On top of that why is it o.k. to see all the blood and violence on t.v. but we can't see or hear anything about sexuality. i think watching someone lose a finger on the evidence (which is so bad it should be censored in the first place for good viewing violations) is more disturbing then my kids seeing boobs on another show. Why is there such a double standard there? i just don't get it could someone please explain it to me? F*** i just don't get it (did you like my censorship lol) i would much rather my kids see sex then violence. But for some reason violence seems to be o.k. and sex not that's dumb.
