"Let's try voting our way out of this, ignoring that the oligarchs/corporate bourgeoisie, fascists, imperial core liberals, etc will do their absolute, die-hard best to ensure that socialism never finds its way to America through the democratic system."
The thing is, "antifa" is a blanket term used by reactionaries to describe any kind of left-wing thought or opposition. So by branding "antifa" as a terrorist organization, it gives them the power to persecute any kind of left-wing thought if they desire. So just think of this as the third red scare, I suppose.
