but has also been used by several on the right, including Trump, as a sort of catch-all reference to any type of left-wing protest activity.

Ding ding ding. We have a winner! This is exactly what they're going to use it for. Any large enough protest will be labeled antifa, and any organization that was part of the protest to help with organizing/funding will be charged with felonies and shut down.

Welcome to the one party state, fascist fucks. Hope you enjoy your egg prices now that you traded your freedom for them.

It's not even an organization. That's what it is. Let alone a terrorist organization. Reichstag fire, anyone?

Nazis invent crises to get permission from the public to hurt people.

They know Antifa isn't really an organization. Which is perfect for them. It is a boogyman they can bring up to justify anything because no one is going to speak up as "official Antifa."

And the media legitimizes insanity by asking obviously nonsense questions

We are all domestic terrorists.
