My son has told me that during his teens there was a short period in his internet life and friend circle life that was pulling him towards right-wing bullshit, certain YT influencers and such that were problematic that "everybody was watching". A few of his friends did end up becoming racist right wingers and he cut contact to them. These were kids I remember from his birthday parties that did have chuddier families and racist distant fathers. His dad has always been not so traditionally masculine (nonviolent, caring, care worker, does housework more than I) which I think did also help, but the pull still happened so it's far more complicated than just raising or not rasing a kid as communist.

The right wing content is there, all the time, for all kids. Most of everything for kids is conservative or nationalistic bs, even school. So I think that peers also can dictate a lot of where people end up. My son was lucky in having enough friends who were kind and also experienced in how nothing is ever so black and white. And his friends were marginalized themselves.
