If a school teacher places the 10 commandments on the wall... congress has made no law respecting an establishment of religion
If the congress or the courts (by legislating from the bench) declare that a teacher can't place the 10 commandments on the wall.. then the government has prohibited the free exercise thereof.
seems pretty cut and dry to me
only a liberal with an agenda could see it otherwise.
No argument from me there. If the teacher starts using paid salary time in class to preach them, though, I think they've crossed a line. (I'm not backing any draconian measures should it happen; but it is inappropriate.)
A voluntary Bible study on their own time after school is a different story, though; the federal/Supreme courts have repeatedly upheld that viewpoint, if I'm not mistaken.
