Profanity A Common Language?

I remember back when I was a kid and watched T.V. or movies, when the "alternative" word for "butt" was censored out,and a movie that showed a guy's naked butt was considered Rated R. These days more and more words of profanity are not being censored on television, and I wonder why some words are censored, but others are not. I was watching National Lampoon's Christmas Vacation on Comedy Central yesterday with my boyfriend. I realized that they censored out the "s" word, but did not censor out when a lady used God's name in vain. Now why on earth would they censor out "s***" but not God's name in vain? It really shocked me. And sometimes when I am watching other shows, such as Teen Mom on MTV, and hear the "B" word, it still shocks me. I have to sit there and think for a second, and that's when I realize that things have changed these days-and not for the better, but for the worse. Parents no longer have to wonder where their children are learning these "colorful" new words. A natural thought would be to blame the kind of people their child hangs around. But where would those friends have learned the words from? Sure, some may hear the words from their parents, but children these days probably learn the majority of profanity from their favorite television shows or movies. Just like how they have these violent video games and movies, "glamorizing" what killing someone would be like. Older teens should know better, but you cannot say the same for the younger kids who are still learning what life is really all about. With the way things are now, I can only expect things to get worse. That is why I am considering not even having kids. I want to have a kid or two when I am married, but do I really want to bring a kid into this corrupt world? It seems unfair. And you can parent your kids to the best of your ability, but that does not mean they'll listen, and you cannot supervise them 24/7, so you never know what kind of things they could be exposed to when they are at school or hanging out with their friends. And once they are exposed to things, they may not want to let them go, which can cause behavioral issues. I think what it really is, is that I am terrified to have a kid and to try to raise him/her in this world. I would always have to wonder and worry about what is going on in their lives, and I do not want to become one of those "over-protective" parents.
