With their version of the identity politics practiced by progressives, alt-right theorists hold that the tribalism to which people are prone should not be transcended but celebrated. As Lopez explains, the alt-right sees society as inevitably "a zero-sum contest among fundamentally competing identity groups." Hence the alt-right is explicitly an alternative to Lincoln's affirmation of the Founders' vision. They saw America as cohesive because of a shared creed. The alt-right must regard Lincoln as not merely mistaken but absurd in describing America as a creedal nation dedicated to a "proposition." The alt-right insists that real nationhood requires cultural homogeneity rooted in durable ethnic identities. This is the alt-right's alternative foundation for the nation Lincoln said was founded on the principle that all people are, by nature, equal.
