I answered this twice already and while I don't mind repeating myself, I'll simply point you back to those other posts so you can inform yourself.
However, I'm always amazed at the misinformation about the Constitution. No where in the Constitution does it state that religion cannot be provided in schools. The religion clause states:
Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.
Notice, it doesn't say "Children cannot be indoctrinated with religion in government-run schools" in fact, you could not be more wrong about the clause if you tried to be. And it "matters" in the sense that ill conceived notions, misinformation and outright ignorance about what the Constitution actually says is still very prevalent, as you have shown. The Establishment Clauses in the Constitution do not say anything about schools - and the notion of a "separation between church and state" is not included in the Constitution, that was lifted from a letter Thomas Jefferson wrote.
I do not want to debate Engle vs Vitale all over again, but don't attribute things to the Constitution before checking it.... if you want to say that the Supreme Court in various legal decisions have supported a separation between church and state, that's fine.
