I never really understood why the society chose to treat several combinations of sounds as something rude and inappropriate. Seems dumb to me. "Fuck" is nothing more than a sequence of sounds. By default, it is no more offending then "Duck" or "Luck". You change 1 sound - boom, you are being frowned upon. The whole phenomenon of "cursing" looks like just another one of those useless, meaningless limitations that society is forcing on people. Fuck society, I say.
So, to answer the topic question - yes, I do "swear"
