I don't always like that freedoms are enshrined in process; checks & balances. It's not perfect; sometimes those processes are used to oppress (voting in the South). The principle though is freedom that goes through process prevents passions of mobs (yesterday's domestic terror)
Can process be misused? Yes, absolutely, thus the need for well-informed voters/participants in civic life. But are the people who attacked the Capitol oppressed by misused process? Even many other Republicans say, no; by end of day that number had grown.
Their sense of grievance is real - and preyed upon. For other circumstances in their lives it's possible sense of grievance is justified; rust belt poverty is brutal for instance. But feeling wronged & being wronged are different.
There isn't evidence of the will of the people being suppressed in this election. It is a nauseating twist to witness, that a group of people carrying Confederate flags into the Capitol building claim oppression by broken process.
In the C-Span livestream & photos yesterday, & the footage that emerged shortly after, it was apparent the crowd was a mix of near-tourist rural supporters, known white supremacists, & militia-like aggressors. At least 1 of those groups isn't interested in sharing fair process.
