One method used to reduce radicalisation in a group session is to have one person ask awkward questions.

As demonstrated by research by Milgram's obedience study and Ash's line study having a single descenter is a powerful tool for helping people resist social pressure.

There is one reason to be at a nazi table which is to be disruptive

Since 2015, after decades of smearing the Mainstream Media, the MAGA Nazis have been coming on the very shows they have been disparaging, and spewing their propaganda alternative facts to regular Americans who haven't discovered, or avoid the Conservative Propaganda Machine. They realized the power of getting on the enemy's platform, and poisoning the water.

That's why AOC, and anyone else who wants to fight back, goes on Twitter. To force the enemy to see the other side, whether they like it or not. If they are totally immersed in the Conservative Propaganda Machine, then this might be the only way they'll ever hear an alternative view.

You can keep arguing that "nobody left on that platform is going to be convinced of anything anymore," but the fact of the matter is there are hundreds of millions of active users there, the vast majority of whom don't give a shit about Musk, and aren't as in-the-know about a lot of the current goings on that most Lemmy users whine about. As a politician trying to push progressive causes, AOC is on there for the same reason Musk is: it's the platform with the most reach. It would be stupid of her to leave the platform. She has tons of followers, only a few of which would follow her to a different platform. It's also the platform her opponents are on, and that's the only place she can realistically call them out on their bullshit and her message be seen.

Does AOC have poor intel/analysts on this?

(Posting under assumption you & I believe AOC dislikes Musk, dislikes Nazis, would wave a magic wand to poof! Twitter if she found one under her pillow; nvm if assumption is misfounded)
