Modesty in the United States

I wanted to approach a topic that's been in the back of my mind for most of the time I've been in Europe: Modesty.

The majority of Americans know that nudity is not an issue in Europe (e.g., topless beaches, naked art) but there are other immodest qualities that give Europe its charm that also seems to make Americans uncomfortable.

Other than nudity, one example is the use of cuss words.  This seems like it's not a big deal, especially for the younger generations in the states.  Most people cuss after every other word (guilty!) and that's becoming normal vocabulary.  However, how many cuss words are allowed on television?
Don't strain yourself, I've comprised a list.
It is acceptable to say:
1)A** but NOT a**hole. Not sure why.
2)Damn
3)Hell
4)Bastard

It is not acceptable to say:
1)Sh**
2)F***
3)C***
4)P***y

If you're wondering why some of these are deemed acceptable, ask the FCC, because I have no idea.
Not only are the words on television censored, but also every song on the radio!  Is there a single radio station that doesn't change or bleep out words? That song by Cee-lo Green about his gold-digging ex-girlfriend was definitely NOT titled "Forget You."  Seriously, think about it!
However, the point of this exercise was to direct attention to the fact that songs on the radio are NOT censored in Europe.  I don't watch t.v. here but I'm willing to bet that it isn't.  There are also no mom's causing ruckus over it either.  Kids will hear bad words.  It's inevitable.

My second example of the prudence in the United States is strangely enough the lack of use of the word "toilet."
This sounds hilarious but it's SO true.  If I was to ask someone at a restaurant where the toilet was, it would make me, and the person I'm asking, feel very uncomfortable.  I feel like the only time you should use the word "toilet" is to tell a plumber that your toilet needs fixing.
Actually one time at a restaurant in France, my friend asked for the "salle de bain" or "bathroom" and the waiter laughed at her and was like "Why?  Do you need to take a shower?"  Why do we try to avoid saying the word "toilet?"
The room with all of the toilets is called a restroom...why?  You're not taking a nap in there.  Everyone knows what we're doing, yet we feel weird saying it.  Heck, my french professor last semester would just be like "Je dois faire pee-pee."  What professor at home would blatantly tell you that she has to pee?

These are only two examples but I think they make my point.  Why is it that Americans are so uptight?  Or are Europeans just very easy-going?  I guess you can form your own opinion.
