Soon, I'm sure. Some Antifa guy meets one of these people on the wrong day and they just blow the asshole away and hope they'll be celebrated as the next Kyle Rittenhouse. If it happens a few times then Antifa won't be so brazen anymore, but you better believe they'll be coming down hard on the Second Amendment along with an all-out propaganda blitz about white supremacists if that happens.
I honestly wonder if that will backfire for the same reason the media's focus on Columbine back in the day directly caused school shootings and indirectly inspired many more shootings with every big name mass shooting (i.e. Sandy Hook or Parkland). You have crazies who want their 15 minutes of fame because they murdered random people, crazy people who want the media to go over them for a news cycle or two. Look how the media obsessed over Kyle Rittenhouse, you don't think someone will think "wow, I can get the same amount of fame from shooting commies/BLM thugs as I would shooting up a school, and people will defend me and praise me and make memes about me!"
