I think peoples reactions to swear words are actually quite amusing. Most people have caught on to the fact that it is not the word itself that causes the offense, but the intent behind the word. Words are just inventions. Most people are also aware that the most common usage of these swear words nowadays is emphasis for the point they are making, NOT as insult.

Use your brain to consider the context the words are being used in, and then maybe you will stop being offended by innocuous statements.
