The founders promised freedom of religion, not freedom from religion in the founding documents. The freedom to practice your religion, not to be protected from the practice of religion.

Huh????

Meaning; the founders rejected any establishment of a state religion. You were free to worship in your own way. This was applied liberally (a word you should like). The Legislature was opened every day with a prayer which is a clear indication that they weren't promoting separation. Being as the vast majority of the people here were Christian you couldn't be expected to be protected from their public displays of their faith. You were not to be compelled to participate, but that's as far as it went.

Of course, as is well known, later activist courts hanging their decisions on a letter written by Thomas Jefferson, and not in the founding documents, hold onto a phrase in this letter that mentioned a "separation of church and state".

How this letter of Mr. Jefferson was elevated to the status of the founding documents confounds to this day.

The expected intelligence.
