Christianity is far too diverse to ever accept a theocratic America.
The Truth was never meant to be imposed on humanity during the dispensation of Free Will; kinda defeats the purpose.
The sheep and the goats will divide themselves without imposition from God, let alone government.
We just ask for a field on which to present our opinions, which we hold to be True (and self-evident, to those that have eyes and ears).
For Clarkson, any society that hasn’t institutionalized his religion, atheism, is a “theocracy”. As for Rushdoony planning to take over the country, someone should tell Clarkson “That Rushdoony, he be dead.” The thought of Rushdoony (when he was alive) plotting anything with Robertson is beyond hilarious, but then Clarkson would have to know something about the men and their theology to realize why his comment is a knee-slapper.
