Progressive Left has sponsored direct action to create social disruption and fear
Such plotting is actual sedition. Fortunately, all these former employees are known, so if they actually try to implement their plans, they can be identified and neutralized. The danger is that many of the methods available to them have been applied successfully to provoke such color revolutions in other countries. The outcomes of such revolutions are universally bad for the citizens of those countries—witness Ukraine, Egypt, Venezuela, and a score of others. We don't want one here.
Besides covert activities, the Progressive Left has sponsored direct action to create social disruption, fear, and to provoke responses from authorities that can be held up as examples of Fascist or authoritarian acts. This approach of provoking a response from authorities is an old tactic of Socialist revolutions going back to the Russian revolution and even before. A proper response to such tactics involves gaining support of the local populations suffering from the riots, property destruction, and other activities, and then making a measured response against the perpetrators.
The FBI demonstrated great competence in tracking down and arresting peaceful protestors seeking an honest investigation into questions around the 2020 Presidential election. That same apparatus can be used to identify actual insurrectionists and terrorists such as Antifa, BLM, anti-ICE, and other violent actors. Portland, OR, or Los Angeles might be good places to start as the normal people there are getting quite fed up with these destructive antics. Mayors, other city officials, and even state governors who seek to impede enforcement activities should also be at risk and arrested if they actively participate in obstructive acts.
At the root of much of the uncertainty, though, is the two-tier justice system the Left has promoted. Our nation depends on a fair and equitable justice system that applies equally to all. An honest justice system is essential to maintaining trust in our system of government. A government of the people must be accountable to the people. If it is not, it becomes a tyranny.
