I feel the same as you, and I think it's worth thinking about. At the risk of sounding very "get off my lawn"-ish (I'm only early 30s!) I think it's related to the fact that our lives are now giant public soap operas being played out in social media for everyone to see. So the swearing at a person in congratulations is telling that how an envious external audience member would feel about their accomplishment, while the person you are swearing at takes absolutely no offense and is very complimented.

Sorry to hear that? That's a little insulting.

Swear words don't have to be negative. Language changes with each generation, words find new uses and connotations and intensities. I for one enjoy my generation's creative takes on conventional swear words!

I did, thanks for the tip though.

I missed the "FUCK YOU" in the text message image. Sorry!!
