I don't like swearing in the street but you can't ban everything you don't like as it is authoritarian. Look at what has been censored and/or banned already: tobacco, alcohol, fat, sugar, the wrong sort of lightbulb, efficient Hoovers, sunbathing, carrier bags, coffee and so on. Some of these things are possibly justified but others, like fat, sunbathing and alcohol have definite health benefits and it should be up to the individual to decide whether to partake of them and the degree to which they should indulge.
Additionally, banning things encourages the puritans among us, the health police and the 'nannies' to go further and further and to punish the temperate for the excesses of the intemperate.
I would ban banning. Hooray for truth and liberty!
