Leftists view every robbery, every burglary, and every dispute that begins and moves to fists or weapons, as governed by the “rules” of a bar fight. They can’t tell who started it, they don’t care who started it, but don’t kill anyone in my bar. Bar fights escalate with fault equally given to both parties. There is no resemblance between a bar fight and some burglar coming in at 2 am waking the family, but they can’t see it. They won’t see it.
