I think the reason that swearing is both so offensive and so attractive is that it is a way to push people's emotional buttons, and especially their negative emotional buttons. Because words soak up emotional connotations and are processed involuntarily by the listener, you can't will yourself not to treat the word in terms of what it means.
Sentiment: NEGATIVE
People ask 'do you make a conscious effort not to swear?' - if you're doing silly stuff you're not tempted to put swearing in. All the comics from my childhood, who were funny without swearing, were the people that influenced me. What I do is quite traditional anyway.
