I voted in the minority above. There is a certain civility and level of formality that is sadly lost, when compared to let's say the 1930s or 1940s as an example. Now to be sure, there is a lot more gained when compared to those times but with regard to how people talk to one another specifically.
Swearing is supposed to be shocking which it isn't, and its supposed to exhibit some level of individualism or independence, which it also doesn't. IMHO, In reality its just another sign of following the pack as it were in most instances.
Have people always used profanity, swearing or whatever? Certainly they have but in every day life it is a lot more acceptable than in the past. The one place it is fairly missing still is in business, but it creeps in there from time to time.
Basically all vulgarity is somewhat vogue these days, look at marketing and what was former "gutter humor" its all over. I f I had a dollar for every time I see "Size Matters" in marketing, with obvious reference to the interesting (and many would say true) reference to intimacy, I'd have a lot more dollars.
So, while I would not really say I am offended per se, because like a lot of people I have a pretty thick skin on the subject. I'm more like saddened because it makes you long for a time where people had generally better social skills and could use other nuisances of the language to communicate their point.
This was not a bash on those of you that choose to use swearing, just my opinion.
