The democRATs have been violent even before they fired on Ft. Sumter.
I make Bleeding Kansas as the kick off to the democrats party being a party of violence. Would anyone propose an earlier starting point? Of course their resistance to Reconstruction, then Jim Crow, were violent, but it took the injection of modern socialist/ Marxist ideology to really turbocharge their violence

The DEMONrat party seems to really HATE those who do not support them, and wants to “put them back in chains” when they exercise their Constitutional right to “freedom of speech”!
