I think generic quotations, on either side, is entirely okay.

I think comparing "ever onward to victory" to "when the looting starts, the shooting starts", i.e. "I approve of and will authorize the use of lethal force for property crimes" is a little of a stretch.

Or "vicious dogs" for people protesting at the White House. These are directly relevant.

"I will use the unlimited powers of our military" - so many problems with this statement.

This is someone making direct and focused statements of threat and intimidation, who has a history of racist and violence-encouraging statements, from "punch him in the face, I'll pay your legal bills" and on.

The challenge is that finding left-leaning populations actively, pro-actively advocating (sorry, "warning") of violent action is a lot more challenging.
