The First Amendment enshrines the right to freely assemble and petition the government for a redress of grievances by prohibiting the Congress from establishing a law that would abridge those rights. That is, the Amendment recognizes that the People have those rights.
But what if a group of citizens uses force to prevent other citizens from exercising those same rights? That is exactly what Democrats who are upset over the loss of their candidate in a free election are attempting. In thier own words:
“We’re exercising our freedom of speech and really want to set a tone for the next few years that there’s a massive body of people … who are very concerned about the dangerous direction Donald Trump is taking our country in. [We hope to] turn the inauguration into as big of a clusterf— as possible.”
Note that the stated goal is NOT to speak their own minds, but to disrupt and prevent other citizens from exercising their own rights to assemble and be heard. They are using force to deny people their rights.
Others have advocated using the Military to delay the inauguration. While this will not happen, it shows that Democrats are not the anti-war pacifists that they profess to be: they have no problem with using violence to achieve their own ends.
The days of civil discourse are over. We are one the verge of another civil war.
