I would agree that the govt decides how rules are defined. The Trump admin will skew rules based on its own biases, preconceived notions, and its self interests.

If the Trump admin is truly interested in combating antisemitism, it should seriously consider revoking citizenship of Elmo and deport him to his native South Africa.

Of course, the Trump admin won't do anything about neo-Nazis because they are one of his biggest financial and political backers. So, it is pointless usual hot air/propaganda by the Trump admin and his minions.
