I've long been thinking about it, and I wonder if it's really that big a deal for children to hear or say vulgar words. I mean really, some people act like children saying **** is the end of the world. I can understand wanting children to have a more refined vocabulary, then again I don't believe that's where the concern for children hearing or saying those satanic words come from, it really seems like idiotic moralists who think such words will leave children traumatized.
Then there's also the matter of sexual content in the American media (not just the US media, but it's primarily what I have in mind right now). Good god, sexual content, and the idea of exposing children to it, causes so much hysteria it's hilarious (but also infuriating). What do they think would happen if children saw penises, vaginas and anuses anyway? That they'll turn into rapists, hedonists or even just become promiscuous? But of course, not as much concern that watching people die brutally will turn them into barbaric brutes and serial killers. Hell, it seems like being a murderer is considered more admirable than being promiscuous, and rape is often blamed on the victim. At least that's how it looks to me, sometimes.
I was already exposed to sexuality when I was a child. I don't have this uncontrollable urge to rape anyone I'm attracted to, which is the excuse rapists, and that other breed of losers with sexual hangups who defend them (maybe they could be called wannabe-rapists), use to justify their actions. Not to mention rape is about power, not an uncontrollable attraction to another person.
So as far as I'm concerned, no word is too bad for children to hear, and they need to be educated about sex as early as possible in their lives. Tell them that it's okay for them to say ****, or ****, but that they should also make an effort to expand their vocabulary. I'm not ashamed of using swear words, but I don't often use them, because I don't often need to.
So, to conclude: I hope one day media catered to children will have swear words and explicit mentions of sexuality, if not full-blown nudity. Notice I didn't suggest suggest graphic violence. It'd probably be a redundant suggestion anyway.
