When I say they don't have the numbers/support ... I refer to the fact that there are far more people talking, than willing to do anything. Regardless of where they are at on the political spectrum.
Also - How many people are able (or willing) to risk their jobs, in the current economy?
NPR is reporting that companies are firing people who have been recorded breaking in to the Capital Building.
There are thousands of people unemployed, now ... just waiting to take those jobs.
Nor do they have the support of the vast majority of Americans.
While it's true that many eligible voters don't vote, because they don't believe there is any real chance of change - that is a far cry from agreeing the system needs to be changed through violence.
As we saw with the reaction to this event, it caused widespread backlash - even people who are friends/family of the rioters are sending information to the FBI.
Nor do they have the support of politicians. Even Trump spoke against them.
It's one thing to rant and rave and support marches that are seen as hateful.
It's quite another to support a physical attack on the seat of government.
