No, but the Government Schools have become enormously political and the NEA which generally runs the Goverment Schools is a leftwing organization that uses the Government Schools to promote their liberal viewpoints.
Using the Government Schools to undermine parents and to indoctrinate progressive social agendas has led many people who have the strength to stand upon their convictions to send their children elsewhere or to choose homeschooling.
Those who understand this use of the Government Schools for below average education and for liberal indoctrination do remove their children from it, but they are still having to subsidize it.
