"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech..."
If one reads those words carefully, one would have to be a leftist, communist, member of the elite media, or ignorant (excuse all the redundancies), to fabricate the concept of the "separation of church and state" from those words. It simply says that the goverment cannot, by law, establish a religion, nor can it prohibit the expression or excercise of a religion by any individual(s).
