"The white assailant was a devout Trump supporter!" *scrubs social media of all said persons pronouns, sexual identification, and pro lefty bullshit*
True, they tried to pull the "Alt-Right incel" card for Connor Betts in Dayton, citing the fact he liked anime and heavy metal (Satanic Panic 2: Intersectional Boogaloo) but then actual close friends of his debunked these myths, saying he fucked a lot of girls because he was in a band and that he did a lot of drugs and was more left-wing than he let on.
Once it became clear that Connor Betts couldn't be effectively spun as a stereotypical incel and that his rampage was a completely apolitical spree killing induced by paranoia, they dropped the narrative and because his kills were in the single digits, they memory holed it.
If Antifa does a larger scale attack or a bombing, it's a lot less likely to be spun effectively. And if the perpetrators explicitly state they're left-wing or if one or more of the attackers isn't a white male, then it becomes even harder to spin it as white supremacists.
After all, the Castle Rock shooting from last year was planned by a biologically female Latina tranny with help from her "non-binary" male friend. That got memory holed because there weren't enough casualties to legally qualify as a mass shooting.
If Antifa does go for the high score or pull a McVeigh in this kind of chaos, it won't be a weak shitshow like Castle Rock.
Sadly it's been looking like there may not be a peaceful solution for years. Worse yet, people seem too subverted and demoralized for a violent one to boot. Only thing I can think of is carefully picking culture war battles while waiting for woke to inevitably implode, which is peaceful solution that could take decades with societal damage that may never be undone.
EDIT -
IIRC there was already an antifa affiliated mass shooter and it got memory holed super fast. So that really wouldn't be enough for legacy media to turn on them. CNN got raided and still wouldn't turn. They've chosen the hill they want to die on.
Yeah, the Antifa-affiliated shooter got memory holed because it was a smaller shooting and his motives were completely apolitical and was more of a typical "going postal" spree killing with no real target in mind.
The kind of mass shooting I'm talking about would be a larger one, think a left-wing Tarrant or Breivik. Casualties would have to be in the 20's or higher for the MSM to not memory hole the whole thing, and CNN letting their place get raided was fairly early in this mess and I think the bigwigs thought they could control this and let the CNN building be an acceptable loss.
This may be the hill they chose to die on before November, but a large bombing or coordinated mass shooting with heavy casualties done by Antifa would be the thing that's way too difficult to properly memory hole at this point. And endorsing Antifa will only infuriate voters to either stay home or vote for Trump
