Confirmed: Team Trump on Facebook posted for Trump supporters to stand against Antifa - and added a giant upside down red triangle. Just google that "upside down red triangle" and see what comes up first.

Red triangle – political prisoners: social democrats, socialists, communists and anarchists; rescuers of Jews; trade unionists; and Freemasons.

Note the Facebook page of the Team Trump account posting the upside down red triangle has a blue check mark. So does the corresponding Twitter account.

Here's the relevant portion on the upside down red triangle. And as mentioned in the first tweet - this wikipedia entry is what comes up first in a Google search for the symbol. This is no coincidence or accident.
