Civilizational and racial nativism differ in whether they define enemies or essence.

Evidence

The anti-radical and anti-Catholic traditions had, on the surface, a negative character that sets them apart from a third and more recent style of nativist thinking. The first two traditions declared what America was not, more clearly than what it was or should be; they aimed from the outset to define the nation’s enemies rather than its essence. Racial nativism, on the other hand, began the other way around. Originally and basically, what may be called the Anglo-Saxon tradition characterized the in-group directly, the alien forces only by implication. — John Higham, Strangers in the Land, 55
