ad_o, with a vocabulary of about half a million words, English has a vast pool of words for every situation without use of 'swear words'. At the same time, there are situations when what appear to be swear words are being used in perfectly 'legitimate' ways. After all, most swear words date from centuries-old linguistic forms of our language that we no longer use regularly (such as Anglo-Saxon English).
That at least is a fairly reasonable assessment of the matter. I'm sure St Paul would agree - Romans 14:14.
As far as I'm concerned, people can swear as much as they like: there's no apodeictic relationship between swearing and having a poor vocabulary and limited intelligence, as one trolling dimwit here keeps asserting.
