The two conflicts were closely linked. Nativists regarded immigrants as bringing all kinds of alien cultural practices with them into America of which they strongly disapproved. One of them was the consumption of alcohol. Most Americans drank alcohol, of course, but a large number of them still paid lip service...
to the idea that there was something inherently wicked about it. They felt that, at the very least, drinking should be discouraged, if not prohibited outright.
In any case, the mass immigration of the late nineteenth and early twentieth centuries into the United States made growing numbers of Americans uneasy, so much so that they sought to find security in notions of so-called 100% pure Americanism, which revolved around white nationalism and Protestantism. In due course, prohibition was added to the mix, marking a clear cultural boundary between the citizens of white Protestant America and the immigrant newcomers.
Though prohibition has long since been repealed, the white nationalism of 1920s Nativists remains a growing threat in American public life. In recent years, a strong anti-immigration sentiment has developed, which has now found expression in the policies of the Trump Administration. President Trump has stated time and again his desire to build a huge border wall with Mexico to keep out immigrants.
The language emanating from the White House concerning immigration has often been hostile, to say the least. In turn, one could argue that this officially negative attitude toward immigrants has created a hostile environment in which white nationalism has flourished. There is a perception among white nationalists that immigration from Latin America and the Middle East represents an existential threat to their ideal of what America should look like. This is virtually identical with the Nativist worldview that dominated American public life in the 1920s.
