Arresting one US citizen and holding him without a charge for 4 years, and denying him Habeas Corpus, cannot be called fascism. Why? Because he is a terrorist?

Have you ever heard the peom

First they came for the communists, and I did not speak out - because I was not a communist;
Then they came for the socialists, and I did not speak out - because I was not a socialist;
Then they came for the trade unionists, and I did not speak out - because I was not a trade unionist;
Then they came for the Jews, and I did not speak out - because I was not a Jew;
Then they came for me - and there was no one left to speak out for me.
