Is a tax-supported school different in principle from a tax-supported church?
A tax funded school is no different than a tax funded church in the sense that it favors one set of ideas; the ideas of those who hand out the funds. State granted tax support creates a biased environment, under immoral standards of foundation (theft and coercion). All people are paying for these things, whether they support them (and utilize them) or not; the favoring and support of one group at the expense of another (everybody else) is wrong, immoral, and violent. A tax funded anything is comparable, if not fundamentally the same to any other tax funded organization.
