dont think anyone would deny they are real words.
i think general hoohaa over swearing is ridiculous...as is the case with many things, by banning it you give it power....
take away its power to offend by making it 'acceptable' and it ceases to be an issue
i do swear a bit, but mostly in extremes of emotion...sadness, happiness, shock, anger etc, not much in general conversation... and i would tend to limit that in a restaurant or something ... this is not for any prudish reason, just dont see the need to add extra words that often serve no purpose.
