They put it all on the line back in 1776. Each of them who signed their name had crossed a Rubicon, and there was no going back.

Understand that by just posting to FR, you are doing something functionally similar. When the left’s death squads (read: Antifa) start their Kristallnacht (they’ve already used this very term), they’ll use boards like FR and Parler for lists of people to doxx, terrorize, and murder. In a way, by continuing to post here, we’re already marked as enemies.
