No one gets sympathy from protestors who fire the first killing shot on the authorities. Syrian peaceful demonstrators turned rebels have sympathy from the world because they were fired at first by Assad. Many people soured on the French Revolution at the time when The Terror occurred after the people started executing just about anyone deemed enemies of the revolution.
No one is against violence if it has to come to it, but on Lemmy it is the usual suspects (I probably don't need to mention what political ideology they tend to be) who want to pull the trigger first on the army and police without ever thinking of consequences (they wilfully ignore the existence of Insurrection act). They are like the 2nd amendment right wingers, looking for any opportunities to fire their guns and live their fantasies, but on the opposite extreme end of the political aisle.
Or, it could be anti-Western actors stoking violence on Americans to maximise political divisions because it will tremendously help if US is thrown further into chaos.
