I grew up during the 60's and 70's, when words such as "ass," "bitch," and the like, were absolutely forbidden by my parents as well as by their peers. Today profanity is much more widely accepted, as evidenced by mainstream media's lessening of censorship regarding certain bits of profanity.
I dislike mustard, and find that the words "fine," and "mustard," are mutually exclusive. (lol)
Nevertheless, just because you have an aversion to profanity doesn't mean that it is anybody's responsibility to avoid it except your own. Your reaction to profanity is your own issue - it doesn't mean that the speaker is any less intelligent just because you happen to get offended.
Just because you can, doesn't mean you have to. This idea that swearing means you must somehow have an insufficient vocabulary or IQ is absolutely ludicrous. Language is there to be used.
It's true that some people use swear words as the bread for their vocabulary sandwich. I prefer to use them more like a fine mustard.
