Government money is the taxpayer’s money. The taxpayer gave the government that money, and the taxpayer ought to have the right to choose how to educate their children, with the tax dollars they put into the system, without socialized government bureaucrats dictating to them how to educate their children. Parents are far better equipped to choose their children’s education that nameless government bureaucrats in State capitols. Especially considering that government public schools have failed America’s children for the past half century.
As far as Ireland, the US government cannot dictate to a private school what religion they may or may not teach. No one is asking to fund religious education. But secular education should be funded in any private schools.
