I find that it is more interesting not to swear at times and also uses up a lot of spare words eg "go forth and multiply" for "f**k" off or "I liken you to the outward manifestation of female genitalia" instead of "c**t".

There seem to be certain sections of the community to whom the F word is totally meaningless in a good old Anglo-Saxon way and it becomes neither swearing nor punctuation. Not that they would know what punctuation is anyway.
