In 1924 the United States government passed the National Origins Act barring Eastern European immigrants from coming into the United States, right about the time when Europe was embracing fascism. If the 1924 Johnson-Reed act never happened, then maybe 6,000,000 Jewish would not have thrown into gas chambers.
The United States is supposed to be a beacon of freedom for all oppressed peoples. Why must we let these know nothing, MAGA hat sporting, troglodytes use national security as a way to mask their not so subtle racism? Let them in!
