The anti American lynch mob known as the Antifa (this week) couldn't resist the chance to go out and pick a fight with Trump supporters. They can't just let people have their opinion or God forbid gather with others of like mind, they have to find a way to disrupt law abiding Americans. See this OWH story and look at the communist flags they proudly wave. The communist flag is the flag of genocide by the way which should show you their intentions.
They want violence.
