There was this beautiful moment where FBI agents complained that it was hard to infiltrate anarchist groups because they couldn't bribe anyone and had to read theory. I think it's that latter part that makes coming back near-impossible for actual wreckers. If it's just someone with one bad opinion they can correct that, but even if someone hasn't actually read theory there's a bar for having that worldview. Then within that bar there's an overton window of what a revolutionary socialist would say and what a LARPer would say and it's ontologically clouded by their actual worldview. There have been somewhat successful splits like we had over veganism, but I don't think we would ever have the problems that a community like /r/antiwork has the same way /r/chapotraphouse didn't. Our whole subculture is bullying bullies and bullshitters.
