When was this?
But also in earlier times, here and there, as well.
There have always been FRINGE groups as well as "lone wolves", who agitated, perpetuated violence and/or upheaval, but it was NEVER like it is now....except for just prior to the Civil War. And even in that era, it wasn't like it is now.
WHY?
Because in times past, few had the time to piss away on crap, they got arrested or killed, and religion played a much bigger part in people's lives!
