People getting pissed over things there parents took as inevitable is basically the definition of progress.
This is the first generation where mental health has been considerd a value. While its easy to dismiss there terminology issues i would say a few things:
1. That its hard to imagine the impact of having a defining life challange constantly talked about by strangers callously.
2. Go back and look at historical "political correctness gone mad" arguments.. even just to the 90s. The ones i have found all seem examples of things we would not dream of saying today and for good reason.
3. These apparently low priority discussions are how you really solve the root causes of issues. Its by figurng out how to support the un supported that all of society is elevated.
