I expect that Antifa has purchased a large amount of wearable Trump memorabilia for their foot-soldiers to put on at any large gatherings, before they start trouble. Someday in the near future, we will be arrested for owning any Trump memorabilia, because of what Antifa did or are going to do while wearing it.
That’s what I would do, if I were them.
They are evil, but their leaders are very clever.
