Atheist libertarians ought to welcome Christians as the solution for caring for the poor. Instead of "to heck with the poor," they can now say, "well the Christians say they want to care for the poor, so let 'em have 'em."

That's about what Ayn Rand did say. (Edit: Actually, it was Objectivist spokesperson Barbara Branden.)

I'm an atheist libertarian who does care for the poor, so I don't actually need you. (I welcome you all the same, of course!)
