The Democrats and Media are exploiting the capital protest to smear the GOP voters as dangerous white supremacist and domestic terrorist
It was no "protest." The people who attacked the Capitol actually were dangerous white supremacists and domestic terrorists. If the shoe fits, wear it.
People do not come to protests wearing combat gear, helmets, and have 2-way radios, batons, and all sorts of other weapons. They do not send messages days before a protest stating that they intend to storm and take over the Capitol and riot, or that a "civil war" is being started. They do not assault LEOs. In a protest, people usually dress in street clothes, carry signs, and chant. There is a mountain of evidence that the criminals who mounted the terrorist attack on the Capitol and Congress itself planned it well in advance. You cannot legitimize what they did by calling it a "protest."
I was in one of the Women's Marches, the one held in DC in January, 2017, while sister marches took place in many cities across the U.S. and some in other countries. The streets were so crowded that it was difficult to walk, and the estimated size of the crowd was three times as many folks as the crowd that attended trump's inauguration, approximately a little less than 500,000:

Yet the crowd did not threaten or attack anyone or any building, including the Capitol, and did no damage. Nobody came in combat gear with weapons.
