What I'm not sure of, though, is what kind of impact there is on the required percentage of people participating when we have media outlets like Fox News, which was demonstrated to have fabricated images during events like the Black Lives Matter protests to make them look as if they were violent.
There needs to be an actual mechanism for the protests to bring about the fall of the authoritarian regime. Unfortunately, in our current context, a lot of the feedback mechanisms that should cause protests to change actual policy and affect the people in power are broken, largely due to the Republicans' efforts over the last several decades to eliminate accountability both from the actual institutions and as a valid concept in our national consciousness.

How can we glorify Thomas Jefferson and teach kids about him saying "The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants" only to then condemn the spilling of any modern blood?

How can we condemn one and celebrate the other without being hypocrites?
