It began as a strange conspiracy theory in American politics. It's since become much strange, much more widespread and much more dangerous. QAnon has spread around the world and driven real-life events that put lives in danger, including here in Canada.
How did this happen? What's behind QAnon's rapid spread and how can we try to convince believers that none of it is true? And what happens if we simply can't stop it and something awful happens?
