Michael Savage, a non-Christian, understands that destroying Christianity will destroy the West. At approximately 12:32 in the below video (Savage Nation, June 22, 2017):
“Unless there is a reversion to the basic tenets of Christianity, the morality, and the ethics of Christianity, this country is doomed, in plain English.”
Arguably, it isn’t a reversion to a generic Christianity that will save the West, but a return to the historic biblical Protestantism which helped build the West in the first place. The first step would be for professing Protestants to actually become Protestant again.
