Why do people swear?
By David Edmonds
But back to the conundrum. If writing F with asterisks alleviates the offence of the full word why should this be? Roache says swearing is best viewed as a breach of etiquette. It is a little like putting your shoes on a table when you are the guest in someone's house. If you know it would offend, and do it anyway, you are guilty of showing insufficient respect.
"It doesn't matter that it's a swear word. Imagine meeting someone who has a fear of crisps, and who finds references to crisps traumatic. If you carry on talking about crisps in their presence, even after discovering about their phobia, you are sending a signal that you don't respect them, you don't have any concern for their feelings."
Using the F-with-asterisks version acknowledges that we are taking the feelings of others into account. By censoring the word we show respect. It's a view shared by Oliver Kamm, who endorses his newspaper's policy on asterisking swear words. Readers cannot help, he says, finding the full word "involuntarily off-putting".
