I'm sorry, but, what?
I know plenty of people who don't play videogames that haven't read a book in years. Most gamers that I know are either working or reading when they're not gaming, and very few gamers that I know are the stereotypical ones that sit in front of a screen all day.
I'm reading a book, doing a job, playing a game for about an hour or so a day, and about to go back to school in the fall. He'd be better off telling people to stop stuffing their faces than reading, it's more likely to happen because most people in this day in age simply don't like reading.
