warn. that is a quote from the book on tierny over the south lake, texas school district. joining me now is timothy schneider. the author of multiple books. professor, good to see you. thank you for joining us. i want to talk to you about this. when you talk and write about the big lie and tyranny and authoritarianism. some people think of the big level. what tends to happen, it sprinkles down and gets to places like school districts where people decide that alternative realities or what they call alternative facts are viable and should be taught to their kids. >> this is right. democracy depends on history.
