Nobody said cloistering. Homeschooling is not cloistering.
And, yes, it would keep your kids safer, because they’re not confined in a gun free building that screams “target”. Not putting your kids in a situation where you know the chances are higher of physical harm coming to them IS keeping them safer. It’s not an illusion.
Homeschooling is not necessarily cloistering. You cannot say that all homeschoolers are not cloistered.
You don't like generalizations about homeschoolers but have no problem with them when applying them to public schools. Pourquoi?
