So why is swearing not acceptable in polite society? I can understand why insulting/saying mean things to peoples face is obviously looked down upon, because it's just a mean thing to do. But why is saying certain words, not in an insulting manner, considered unacceptable? What about words that are synonymous in certain contexts, consider "fuck" and "intercourse", one is rude, and the other mature. So how the fuck did we come up with swear words?
