Well, they are challenging the separation of church and state at every turn. Not just legally, but as pseudo-historians. They actually believe there was no intention to separate church and state by the founders.
They would like to refound the country as a Christian nation based on what they understand as Christian values, forcing us all to adhere to them by law.
That is as un-American as it is possible to be, in my opinion.
