Not only that but it is most definitely organized, even funded, from inauguration rioting to disrupting town halls.

It did not take very long to get from “Punch a Nazi!” to “assassinate a congressman.”
A great deal of spittle has been deployed in the debate over whether or to what extent the Left’s recent indulgence of its penchant for violent rhetoric can be linked to the shooting of Representative Steve Scalise and other members of a Republican congressional baseball team by an angry Democratic activist and Bernie Sanders partisan. But the relevant question here is not violent rhetoric but violence itself. The violence at Berkeley and Middlebury did not lead to the shooting in Alexandria — they are part of the same phenomenon: The American Left has embraced political violence.
More precisely, the Left has embraced “anarcho-tyranny.” (Yes, I know what kind of man Sam Francis became; his phrase remains useful.) The anarcho part: Progressives including mainstream Democrats have embraced the sort of violence that has been directed against the likes of Charles Murray as an instrument of liberationist politics. Representative Val Demings, a Democratic congressman from Florida, shared her view that the riots greeting Milo Yiannopoulos at Berkeley were “a beautiful sight.” After a physical attack on white nationalist Richard Spencer, Jeremy Binckes of Salon wrote: “Maybe the question shouldn’t be, ‘Is it okay to punch a Nazi?’ but, ‘If you don’t want to be punched in the face, maybe you shouldn’t preach Nazi values to the public?’” A lively debate about the ethics of using violence to suppress certain political views ensued. Short version: Free speech did not experience a runaway victory.
