I'm all against censorship, it doesn't make sense for me.
Here in Argentina you can see boobs all day in cable, though not porn, there are channels that are kids friendly, cartoon cannels for example, parents make a big deal if their sons says f*ck but they don't say a thing when they watch Billy & Mandy, and THAT'S nasty and uncalled for, it has violence and the Death is one of the main characters... kids even look at Family Guy in cable channels and their parents don't even think about it because they're cartoons! I know that that doesn't happen in EEUU but here happens a lot.
And there's always parent control, if you contrated a porn channel (that only plays at night) you can put a password and children can't have access at it, so what's the problem? Really, parents sometimes complaint about all the wrong things and don't really look what their childrens are REALLY doing...
