How did the term "nativism" come to be used for an ideology which, in the US, is all about the descendants of colonists and immigrants who massacred and displaced the country's native population?

This thought was prompted by seeing descriptions of the new "America First Caucus" as a nativist movement. While true to the meaning of the word as it's used, it struck me as a strange word to end up with this meaning considering just how non-native to the US anything "Anglo-Saxon" is.
