"In fact the following provision of the 14th Amendment reaches back and makes the 1st Amendment apply to the states:
"No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction of the equal protection of the laws."
This then makes the five freedoms guaranteed in the 1st Amendment --- religion, speech, press, assembly, and petition --- apply in the states."
As I point out in the post, the Establishment Clause CANNOT be regulated by the Federal Government, as the Establishment Clause forbids the Federal Government from doing so. If you apply the XIV Amendment to the I Amendment, then the I Amendment is overturned. If the I Amendment is overturned, then what law is there to impose on the states? It's a paradox. Remember "Congress shall make no law RESPECTING..." that means the Federal Courts can take no case respecting an establishment of religion, unless it's Congress making a law.
The XIV Amendment on the Establishment Clause has been used by Secularists to tyrannize people into removing Ten Commandments monuments ad school prayer. It has been used to tyrannize, not liberate.
