I think it already is blowing up in their face, and agree fully with your sentiment. While atheists dont depend on religion to define their morals, they get the opportunity to self-define their morals. A narcissistic egotisticial born-with-a-silver-spoon person like Trump is a wolf in sheep’s clothing parading as one of them. He decays or corrupts everything he touches, and the GOP and evangelical Christians have been rubbing all up on him for 7 years. Both groups are in crisis these days.
The GOP has no true platform beyond revenge politics, and the churches are bleeding congregation members… people leaving either because they aren’t on board the crazy train of their church peers or leave because they’ve allowed their beliefs and morals to twist out of whack in conflict of scripture.
