Ok this may sound stupid but I think there are a lack of words you can satisfactorarily substitute in for swear words. I know this as I gave them up for lent.

Also many people (example A: PG) with good vocabs still choose to use them.

If there were a word that you regularly substituted in for a swear word, wouldn't it then become a swear word? Do you mean words like "heck" or "freakin"?
