Simply home school and don’t worry about it. We did for 20 years and have a family of well adjusted, normal children. Married, college degrees and doing fine. All are conservative, but are so of their own free will.
We’ve done the same. Our perfectly normal kids all have multiple pocketknives (more than I can count), hunting knives, bows, arrows, toy swords, toy guns, BB guns and a 20 guage shotgun that fires real shells.
