>FWIW your comment feels valid enough up until your final sentence, you just didn't need to attack "the newer generations".

Why not? He's exactly right, in my experience. It's definitely been my experience that the newer generations (of Americans) are much more likely to casually use swear words, usually the f-word, in regular conversation, even at work. I hear it all the time with my American colleagues. When I was their age, no one talked like that at work, or really in general except maybe in private with their closest friends.

Another big difference is mass media: when I was their age, American TV did not allow swear words. But in the last 10-20 years, it's completely changed, and it's pretty common to hear the f-word on regular TV. So of course the "newer generations" are going to reflect this in their casual speaking.
