Why the double standard with Abrahamic religion?

143. "roughly half of which were vaguely deists" -- nope

Much as it would delight me to believe so, the facts just don't back up the idea that the Founders as a group were religious liberals. A few heavy hitters were deists--Washington kind of, Franklin, Jefferson--a survey of the religions of the Founders shows they mostly were pretty conventionally Christian, mostly Episcopalian or Congregationalist, and quite a few were devout. Of course comparisons of the social role of religion in the 1700s and now are inherently flawed. It was the Baptists back then who wanted to disestablish the Anglican/Episcopal church from state authority (as opposed to the theocratic bent of today's rightwingers). The roots of the movements to expand civil rights, provide for society's poor and oppressed, and end the scourge of slavery in the country were based on the works of very religiously devout citizens in the late 1700s.

I agree the country isn't based on Christianity, of course, but we shouldn't blind ourselves to the irony that to a great extent it was religiosity that made the US such a progressive country in the early Republic.
