Exactly which democrats are you referring? The president, democrat congressmen, governors, state legislators, mayors or are you referring to far left political organizer such Angela Davis, or Alicia Garza of BLM?
This reminds me of the 2017 protests and riot in Charlotte where hundreds of white supremacists gathered to protest the removal of Confederate monuments resulting in the death of 2 police officers and a protestor. Democrats were quick to blame republicans but in fact the violence was due to rightwing extremes, the Proud Boys and some Klan members battling some locals and Antfi, a violent leftist anti-racist group. The two days it took Trump to condemn the white supremacists gave democrats all they needed to condemn republicans for the riots and deaths.
This is a sickness that has infected the country. We blame the opposition party for the misdeeds of the most extremist supporters of the party and we do it over and over creating an ever widening gap between many millions of Americans. Nations like China and Russia fan the flames of hatred and division by planting false news stories on social media. Neither party will condemn those stories as long as they see them as beneficial. I believe eventually the nation will fail as we become more and more divided. The strength of the United States lies in the fact that we are united. As one philosopher said, United we can accomplish anything, divided we can accomplish nothing.
