The tax the churches crowd sounds like another misery loves company bunch.   To those of you who don't know the US Constitution, the First Amendment in regards to religion is :

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech..."

Original intent and text tells us this means that the state cannot establish a state religion;  nor can it prohibit the free exercise of any religion, nor can it prohibit free speech - as long as no religion violates any person's rights.
