Which group did nativist specifically target as a threat to "american culture"?

Catholic and Jewish immigrants.

Explanation:

Nativism is an ideology or political and social thought that defends or privileges those born in their own land and therefore rejects foreign migrants who come from abroad. "Nativism alludes to the idea that states should exclusively inhabit members of the native group (" the nation ") and that non-native elements (" foreigners ") are a fundamental threat to the homogenous nation-state."

Nativism is one of the expressions of demographic nationalism where foreigners are never well received either by the whole of society or by any of the ethnic groups of that society when considering foreigners different from them, by geographical origin, religion or any other socioeconomic feature.
