Sure, yes my friends use profanity, but I'm not just basing this on my life. I've mentioned a few other notable folks who also have explained that view, plus if you are on twitter or listen to podcasts, well you'd notice profanity is not so taboo for a pretty large portion of people.
It is indeed an interesting topic, but from my point of view it's pretty much just don't worry about how people talk.
So pretty much your main point for why you don't like it is because its "vulgar" and as mentioned a bunch you want it to retain its "edge"? My solution, become more vulgar and edgy and you won't mind the words anymore. =P
