I'm not an American, but it's interesting to see how strongly people from the States react to swearing. I know that for every 10 guys thinking that the usage of the word "fuck" is unprofessional there is at least one George Carlin (https://www.youtube.com/watch?v=AsZwRirDOYQ), Lenny Bruce or Bill Gates (http://philip.greenspun.com/bg/), it just seems that this "puritanical" point of view has gotten stronger and stronger lately. I'd be curious about the underlying reasons.
