I propose to kill them socially. Shun them from any collective gathering and let them live at the edge of society as they wish. Are you antivax? Very good, no medical treatments for you. If you don’t believe in vaccines I don’t see why you should be using antibacterials or chemo treatments.
You don’t like the laws protecting the right of minorities? Don’t ask for law enforcement to show up at your house should you ever be robbed or attacked. Either you respect the law or you don’t ask for its support when it’s convenient to you.
Are you a dickhead to others and cannot live normally around people different from you? Go live in the woods with someone akin to you and you alone.
We would very quickly loose all the deadbeats who are a menace to a civilised society and we wouldn’t even have to get physical with them.
