The original series of speeches and sermons by the former Nazi pastor Martin Niemöller’s mentiones the Incurables, Communists, socialists, schools, unionists, democratic socialists, Jews, the press, and the Church. but explicitly avoids mentioning the Nazi party started with felons and foreigners.

The original German poem omits the felons, foreigners, incurables, schools, press and church.

The American English version further omits the Communists and originally tried to replace “unions” with “industrialists”.

If you are going to project the “first they came for” concept onto the USA you can either start with the spirit of the poem:

First they came for the indigenous peoples

Which sets the start date of the poem to at least ~1850.

Or you can start with the letter of the poem:

First they came for the Communists

Which sets the start date to at least ~1950.

Some chucklefuck downvoted this.
