The Antifa "A" logo has the letter A inside a circle. Could be he didn't bother. Could be he meant something else. Most of these shooters have no steady ideology and by their social media, seem to bounce around between a lot of mixed ideologies. Perhaps they're just unstable, like their families.
The circled A has long been an anarchist symbol. I don’t think it’s an Antifa logo.
The A here is probably for Awake his ‘stage’ name.
Could be it was just an A to stand for his rap name, “Awake the Rapper.”
But the press doesn’t want to bring that up because when you think about it, the word is a play on “woke.” And that points back towards Antifa @ their ilk.
His mom’s website, though, gives more hints, in that she is linked to a religious cult/church that is a promoter of gay marriage. That is pretty woke.
