Yep. We have filters on our satellite and only the wife and I know the password. Our kids know when something is on that they shouldn't watch and take appropriate action... they turn it off. If something inappropriate does come on we usually say something like "Ew! That's nasty" and change the channel and explain to them why. You can't shield them from everything, so you have to equip them to deal with all situations. So far so good with ours, knock on wood.
Now, to say the 50s were so much better... I have to wonder?
For one thing, the place wasn't so crowded. There are twice as many people in the country as there were then, so, half as much space today. Hard to go anywhere without running into other people. Pack 'em in like sardines and there will be discord. There weren't outlets for news (and gossip) like there is today, so you just didn't hear about the problems in society as fast as you would today. Now you hear every story from every little podunk town. That stuff happened in those towns in the 50's too, but you never heard about it.
Second, there was foul language back then, too. Many of the old dudes I met cussed like drunken sailors when their wives weren't around. They also made derogatory remarks about women and were extremely racist. So, while the actual words may have changed the intentions of those words have not.
Third, there were lurid images back then, too. As the old dudes die off, I get to clean out their houses from time to time. Guess what? They all had something stashed somewhere that had lurid images in it. You usually find it in the garage or tool room, in the bottom of an old fruit crate with some cigar boxes full of stuff on top of them. Their wives usually knew about it but never let on.
So, I think the only differences between then and now is that stuff is not hidden as much AND there is twice as much of it due to the doubling of the population. It was there, but people tended to pretend it didn't exist. That, or they were extremely naive.
