N0mesorah,
They are a real organization to Trump and his supporters. In fact ,the Trump campaign sent out an “ANTIFA ALERT” to supporters on Saturday as part of a broader effort by President Trump to instill fear of civil unrest and left-wing vigilantes.
This is even as he says his crisis management strategy where he lied for months about the COVID19 pandemic is primarily aimed at maintaining calm.
Trump needs to create a ghost enemy on the left to match the real terrorists – White supremacists organizations on the right.
