As long as we're advocating shooting folks without the benefit of a trial, how about we throw in people who don't re-cycle, or who drive gas guzzlers, or Methodists, or tailgaters, or bald people, or people who live in Boise, or.....
“how about we throw in people”
People use such arguments all the time. It’s a puzzlement. Is its fatal flaw really not obvious to you?
