Well, this particular individual wasn't Gen Z. It was an older person. Probably my age, and I'm Gen X. An older member of Gen X, which means if he was a year or two older than me, then he's more likely Baby Boomer. But when you're that close to the line, does it matter which side you fall on?
My beef is that it's a shallow thing to point someone to some "research" that some unknown or unspoken group has performed, then when your communication partner inquires for more information, your response is, "Do your own research." And to say it to someone who wrote a book based on their own research is simply moronic. Those people make points. They don't have points to make. They're agitators and trolls. To them, I say, "Buy my book, then we'll talk."
