Let me understand this

You can have openly bigoted statements and behavior in your repertoire, but the only outrage is calling out that bigoted behavior.

First they came for the Socialists, and I did not speak out—
Because I was not a Socialist...

It strikes me that many of the journalists reporting on this story approach it as some kind of academic exercise with the outcome having no more import than the result of some video game. An issue to be exploited for whatever benefit it might produce.  And then its off to the next issue du jour, never having really comprehended the true consequence of the concept.

These people behave as if it most assuredly will not affect them if openly bigoted attitudes are somehow able to prevail again in modern American culture.  The impression is that you would be able to sit back in your easy chair and tut tut about the way they are treating those poor blacks/women/Muslims/immigrants/disabled/Mexicans/others but it won't impact me personally.  So why should I become personally invested in this discussion.

But for those in the affected groups there is no other way for it to be taken but personally.  And those who don't understand that are simply part of the problem.

...Then they came for me—and there was no one left to speak for me.
