> But that, once upon a time, and it wasn't too long ago, there was a thing known as "civil discourse" in this country. In which (and granted the boundaries are fuzzy hear) -- in itself the mere fact of having an unpopular (or difficult) opinion on the state of the world ... did not run such an alarmingly and dysfunctional risk of getting you shut down in form or another as it does today.

This is so disconnected with history its almost delusional. Go read about how civil rights advocates were treated in the south, or gay rights advocates a mere 30 years ago. Go read about how distributing information on birth control was a crime, or how being a socialist brought the state down on you. Go read about the labor movement before WW2, and how many workers and would be reformers were shot for their words.

For a decent chunk of the 20th century, straying outside the bounds of “civil discourse” wouldn’t get you “shut down”, it might get you killed or jailed.
