Oddly, the evangelical movement is strong enough in US to distort our politics. It is characterized by a zealous intolerance of anything seen as heretical. The right in this country is in bed with the dominionists (who seek to undo any separation of church and state, and have sharia-like ideas of governance). The combination is proving quite conducive to fascism.
I think the movement has such a hold because its leaders have perfected the art of convincing their adherents that moral society (not to mention the eternal disposition of their immortal souls in heaven or hellfire) is under siege by a fabricated mindset reminiscent of the satanic tinge the Protocols, a seminal antisemitic calumny, had. It was a driver for the Holocaust and pogroms further east. Social and political liberals, which now includes the center, are portrayed as the carriers and agents of moral plague.
This siege mentality combined with an extortionate avarice, still illustrated by the success of Save America sucking up money into that man’s hands, creates a Stockholm syndrome. They’re effectively recruiting younger citizens into the cult, so here at least I see lasting danger from the coalition of activist churches and authoritarian politics.
