> How many of them are there?

Indeed, this reads as a case of somebody forgetting that the news doesn't report what's absolutely normal to everybody. It reports what's unusual. (Plus all the articles that misrepresent people's opinions either deliberately for clicks, or accidentally through lack of understanding, sometimes due to being given a quota of articles to rush out per day.)

Perhaps the universalizing mistake is going a little bit in both directions here.

There's a huge current trend where people love to tar an entire generation with the same brush. When a person a generation or more removed (in either direction) says something we personally disagree with, it's become the norm to put down that entire generation as though they share the same viewpoint. It's a very unfortunate trend IMO because it often comes across as arrogant and/or patronising.
