The protesters get violent causing the government to crack down on them and thus proving the protesters’ point that Trump is “Hitler”. The protesters are creating the situation about which they protest.
Actually terrorism relies on the same principle, only writ large: now way can a few hundred people overthrow any but the smallest nation, but they can provoke an overreaction that causes the people to turn against the government or the government to retaliate in a way that causes it vast amounts of tamale WRT blood and treasure,
What the Trump administration is doing brilliantly is trying to keep the left from framing the discussion. Once the other side gets to choose the language and the frame of the debate, you have lost, no matter how good your logic or brilliant your operational strategy.
Fortunately, I'm pretty sure Bannon and others in the administration have read ‘Rules For Radicals’; and since we conservatives behave in the fact based real world pretty effectively the left has much more of a fight on its hands than it ever did in the GWB or Nixon administrations.
