In Knightstown Indiana, there is a Christmas Tree on public property, the objection is not about the tree, but the cross at the top of the tree. It has been there each Christmas for many years, with the blessing of the town’s citizens. Only one person is objecting and filing suit. Okay, one person, or ten, or even a thousand objecting, is not important, because, as a whole, the people have decided they want the cross displayed. Nor is it important that the cross is displayed on public property. The Frist Amendment is not about who, what, where and when a religious symbol, or worship is displayed or takes place.
The First Amendment is elegant in its simplicity of meaning; Congress shall make no law. A statement so basic, so complete, any 5th grader can, with certainty, define the absolute meaning of the sentence, and apply it correctly to the rest of the amendment.
The Indiana Constitution states;
Section 3. No law shall, in any case whatever, control the free exercise and enjoyment of religious opinions, or interfere with the rights of conscience.
Note both the Federal and State Constitutions agree, that no law shall be passed prohibiting the freedom of religion. Note neither Constitutions, place, or allow to be placed, limits on where, when, or how, this freedom is practiced.
Random searches of State Constitutions, turn up similar wording for each state researched. It would not be unreasonable to extrapolate, that all 50 States have, within their respective Constitutions, an absolute right to freedom of religion, and that the states have bound their legislatures from passing any law, as to location of the practice of freedom of religion.
The Federal and State Constitutions are limits on governmental interference in religion, not limits on where. And yes, this individual pays taxes that are used on public land. We all pay that tax, and without going into specifics that will highjack this issue, we all object to how some of our tax money is spent, so be blunt, grow a pair and suck it up cupcake.
