The only way around this is to just keep stuff compartmentalized (work vs non-work, social group x vs social group y, relationships vs family, etc)
Or else certain kinds of people will form these "bullshit networks" that are sort of like mafias. Then they use the leverage that comes from it to bully other people around. It's the same network that amplifies a cancellation attempt
I've seen this play out in offices, friend groups, over extended family, etc. The best way to address it is to spot this kind of person, keep them compartmentalized, and give yourself the ability to walk away at any time as a check on their behavior. Or else there's no real bound on how awful they can be
My friend was devastated, he had to stop going to his classes and feared that nobody would hire him, professors would hate him (since students already did), and that his life had ended. I spoke with him and assured him that wasn’t the case but to be honest I wasn’t sure either.
I don’t know the details but one year later she was suspended for a year for falsely accusing him, my friend graduated and promptly found a job.
All this to say I’m awfully scared now of the risk of my interactions with women being used in the future as a false narrative to cancel me. I’m happily married and due to life stuff I do have to interact with young girls and women. Because of this I try to be as distant as I can and limit any interaction that doesn’t involve multiple other adults.
I learnt that even if you do nothing wrong you can always be at risk, so I just try to minimize that risk as much as I possibly can.
Maybe just keep a war chest and slam them with a bunch of lawsuits if they get annoying. Or at least, that's how the professional bullshitters like Trump solve this problem
