I'm not going to blame the Dems for the Dayton shooting, or the Scalise shooting - crazy people will always find something to channel their anger into.
But fundamental to the progressive movement is resistance and activism. They form mobs, break shit and assault people. Point is, I think we are approaching a tipping point for a lot more violence....from the left. Expect many more protests, and expect them to become increasingly more violent because all the Dems and their media ever do is rationalize how their grievances are justified while ignoring the lawlessness.
Just look at that Democatic Socialist rally and you realize there are a lot of mentally ill people on the radical left. You've literally convinced these people that Trump and Republicans are an existential threat. I'm sure they're harmless - let's sit back and see what happens.
