Ever heard this quote? "Intellectual laziness and the hurry of the age have produced a craving for [instant gratification in media]. The torpid brain has grown too weak for sustained thought. There never was an age in which so many people were able to write badly."
The specific profanity element aside, that's what this conversation reminds me of.
The funny thing is, that quote is from the year 1891.
Xkcd did a wonderful collection of these timeless "The useless youths don't take the time to talk proper!!" rants from the turn of the 20th century to illustrate that
every generation believes the following generation is failing at communication and life in general. You can read them here:
https://xkcd.com/1227/ Personally, I think this is a natural result of the fact that we tend to judge our generation based on ourselves and our friends, while judging other generations-- particularly younger ones-- based on the worst examples that we observe (in person or on tv/internet/etc). Combine that with the fact that language is constantly and quickly evolving and an older person might not understand the language that young people are using to communicate among themselves, and you have older people convinced that the English language is positively doomed. Of course, there are stupid and careless people of every generation, so sometimes people really do use language poorly. But in general, sit back and relax, folks. The kids are alright.
But regarding the original topic of profanity, I do think it's partially regional. I met two women from Boston on the AT this year and felt myself literally flinch a couple of times when I first met them and heard them cussing people out over mundane things. It took a mutual trail friend to talk about how nice they were before I realized that the profanity was just a normal part of their speech and that it didn't mean they were angry or insulting, and in fact they were nice ladies. I also think it relates to how most popular TV shows these days are not network shows that censor profanity. Instead it's all Netflix, HBO, Hulu, etc. where there's almost a competition over who can be the most profane and "edgy". I think sparsely-used profanity can pack a meaningful punch in conversation or in comedy, but when practically every noun in a sentence is modified by the adjective "f*****g" the words just become noise. Not a fan. There were definitely people like that out on the trail this year, but I didn't observe it to be a generational thing.
