The First Amendment: 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.

Citizens are allowed the free exercise of religion, but classrooms seem to feel free to talk of anti-Christian content and when their is an attempt to restrict such agendas, "free speech" is claimed, however, when the tables are turned, parents are expected to bow down and comply to restricting their free speech exercise.

"And I beheld another beast coming up out of the earth; and he had two horns like a lamb, and he spake as a dragon" (Revelation 13:11).
