I think you're being a bit too literal about the word "culture" there. It's like saying social media isn't "social." That's just what the thing is called.

But I'm also often surprised by how much people underestimate the impact of what people see ono their screens and what they do in real life. Just as a quick example that I included in the article, Payton Gendron killed 11 people in cold blood last year because of things he read on his screen.

I don't understand where the idea that there's this clearly defined line between people's attitudes online and their attitudes in real life comes from.
