No, no it wasn't. It was based on a haven free from oppression. Quit confusing patriotism with nationalism.
I am not the confused party here. Patriotism is the expression of nationalism.
And yes, it was.
No, it is not. When the United States was formed did they pick only to allow immigrants from a particular race? Religion? Language? Ancestry?
I'll save you the time, no they did exactly the opposite.
The Naturalization Act of 1790, the very first legislation by the first Congress:
[United States Naturalization Law of March 26, 1790 (1 Stat. 103) provides the first rules to be followed by the United States in the granting of national citizenship. This law limits naturalization to immigrants who are free 'white persons' of good character. It thus excludes American Indians, indentured servants, slaves, free blacks and Asians.]
To make America great again, we must return to this specific legislation.
