Actually, as the far right militia groups and their fervent glorification of religious cults (such as is evidenced in the Waco incident), culminating in the Oklahoma City federal building bombing is probably much closer to anything actually resembling domestic armed insurgency and rebellion than anything that happened in the '60s.
No, IMO. Way too small an insurgent group. You have to have more people involved than that, and less ......obviously radical and violent.
The '60s near-miss was almost all college students, a very mainstream population (which is why the openly communist leaders got nowhere with their doctrines: we just wanted to stop the war).
And the French Revolution was wholly initiated by intellectuals, doctors, lawyers, clergy, and other well-educated ....idiots.
It got out of hand, and the mob ruled and the crazies and power-hungry who grabbed power. Hundreds of thousands died by guillotine, drowning, and civil war.
Such a problem in revolutions..... Stalin. It will happen here, too.
