That is because you are a man that has: etiquette, class and decorum. Qualities only some people have or will ever acquire. I rarely watch a movie that has swear words throughout. The rubbish that they make today which they call movies is a disgrace.

Michael, people can have etiquette, decorum, decency, kindness and many other positive traits and still swear. I really don't understand how a sound can affect people so much.
In my lifetime, I've been around a bit and seen a lot. I've dined, many times, with some of the most eminent professors at Cambridge university in some of the most amazing halls. These are supposedly "prestigious" events that undoubtedly have lords and such in attendance, and whilst at the dinner table, people have impeccable etiquette. I suppose that goes without saying. However, catch any of these people at a bar or on a trip to Iceland or the Alps and it's a different story! They all drop c-bombs and swear like anybody else I've heard. Does this make them bad people?
I've also been to more black-tie charity balls than I can count, and the same thing applies. These events have the supposed "cream of society" in attendance, namely surgeons, barristers, business magnates, etc, and most of them swear even whilst at the ball. I distinctly remember talking to a heart surgeon once at one of them, whilst circling the room, and he was a real barrel of laughs. You could tell he loved his job, but guess what? Holy shit, he swore a lot! I could give dozens of examples like this.
Here's a random photo of me at a ball.
I suppose this is a long-winded way of me saying that this strict code of etiquette thing is a man-made concept from a by-gone era. Most people don't care about any of that stuff anymore, except maybe the Royals and a few other titled people (and even then, are we saying that Prince William and Prince Harry and other royals don't swear?).
Like I said before, class and language use doesn't really mean a lot. What matters more than anything else is how a person behaves and holds themselves. People who are obsessed with class are often very snobby and arrogant, in my experience.
