“They want civility, let em police themselves!”
And here’s the irony; they would do a far better job at greatly lower cost. You can’t force social norms on large groups of people who don’t accept those norms absent sending in an armed force. Why go there?
For all amongst us who have escaped from such neighborhoods and areas, and our like minded fellow citizens who are foreign born legal immigrants, who escaped from even worse situations...WE all “go there” because tolerating such things is not an option in our society.
The “large groups of people” unable or unwilling to abide by our social norms are more than welcome to leave.
