I agree that there would very little push back from the public; their ox has not been gored - yet.
First 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 for me
Martin Niemöller (1892–1984)
I was saying that back when the deeming first hit, and people said I was crazy...it would be pretty easy to criminalize it on a state by state basis, and I don't think there would be much pushback from the general populace.
