Seriously though acon, I have conflicting views on this. I'll be the first to tell ya that yes on many occasions I'm the worst offender. I TRY to restrict my salinity to duress (e.g. highway situations) and when I am hanging with my buds, as our common parlance comprises it.
However, just down the road there is actually a city ordinance banning public profanity, which I think is a good thing. It really torques me for some reason when folks cuss in front of women and children, or people who would be genuinely offended, and I always feel real bad when I let slip...
Didn't used to feel like that a couple years ago; must be gettin' old... ;)
