Interestingly, french and russian revolution are among the bloodiest revolutions. I wonder if french revolutionaries and russian revolutionaries who killed many civilians and even innocents and children are referred to as "terrorists" anywhere. I doubt that.
Whats most interesting part is that time following French revolution is often called "Reign of Terror" but revolutionaries Sieyes, Lafayette, Marat etc are never called terrorists.
Even likes of Bertand Barere and Louise Antonie are not called terrorists but they were single handedly responsible for deaths of massive number of civilians.
