I keep telling you I am not an American, and things don't always or often work that same way outside of America. Though there are parts of Europe struggling with similar issues now. None of what you are saying makes that much sense in the UK. There are young people who want radical right wing policies, but they aren't voting for the mainstream conservative party. They are voting for Reform UK, causing the right wing vote to be split. This split is a large part of why they lost the last election by a country mile. Meanwhile Labour moving right, combined with repeated scandals by the conservatives has lead to even life long conservative voters changing sides. Them moving right has also lead to them being critical of transgender people. Our Labor prime minister has gone so far to say that even transgender women who have a legal certificate should not use Women's spaces. It's crazy honestly. This is the same guy that's pro-nationalization and pro-regulation.

You keep saying we even though we aren't even in the same situation. It seems all you care about is the USA. Honestly I personally think the USA needs to hurry up and collapse already since that's what seems to be happening anyway, and the slow collapse will just cause more issues.

If you want people to cooperate better and get along together the best thing you can tell them to do is to not get involved in politics at all. Politics is a lot of what is causing this division and "atomization" as you call it. Neurodivergent people are easily radicalized by extremists of both sides both alt-left and alt-right. You are better off telling them not to get involved at all if you want people to follow community and stop forming cliques. Of course you aren't going to do that, because you actually have an agenda yourself. I wouldn't tell people to do that either for the same reason. Although actually you could do some targeted voter suppression and disenfranchisement with right-wing people if you wanted to steer things in a left wing direction. If all you care about is winning the vote then you need to start employing and using the same tactics as the alt-right use against everyone else. Pushing radical ideas and policies would be a good step in the right direction, since that's exactly what the alt-right do.
