Ridiculous. I am anti fascist, and I have never heard of any of what you are talking about.

I oppose fascism.

That does not magically infuse into my brain mysterious connections to groups of people, nor instantaneous knowledge and mastery of tactics from nazi groups...

That would be actually kind of cool, but no, sorry to disappoint you.

The objection is the administration is inventing a group wholesale in order to designate those who oppose their policies as terrorists. The executive order can say whatever, that doesn't make it factual.
