Here is another example of a crazy pro-algae (likely paid) protestor.

The sign says, “First they came for the algae…” which is in reference to a famous post-WW2 statement about Germans not speaking out against the Nazis:

“…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 for me.”
