It’s not such a black and white issue. As for the truancy laws, parents have a right to put their kids in private school or homeschool them, so they can avoid the public schools if they want. Also, while the schools are funded by taxpayer money, the taxpayers also get to vote for their school board members. If they don’t like the policies coming out the schools, they have the power to instill new leadership.
I'd say all three need to join the service, get deployed and return as young men who fought for their country in uniform. They'll no doubt have the added benefit of not running into anybody like the effeminate Mr. Kaufman while they are on active duty.
