Since I apparently “lack nuance” and anything I say on this topic is automatically attacked, here is another piece from someone who actually understands how self defense works in the real world.
I posted Mike Williamson’s excellent piece earlier. Here is one from author Peter Grant. If you don’t know Peter, he has been everywhere and done everything. He’s been a warrior and a priest, and he has personally looked into the abyss of human evil.
Peter also has a book out which is about his time as a prison chaplain. I recommend it, as well as his science fiction novels.
