I think people confuse individualism with narcissism. There's nothing inherently bad about individualism: Self-reliance, independence (vs. interdependence), etc. I think these are mostly seen as good traits, at worst neutral.

What we saw building in the last decade or so, and come to a head in 2020 is out-of-control narcissism: Selfishness, entitlement, lack of empathy, this belief that life is a movie and you are the main character. This is the kind of thing that not only estranges one from family, friends, and society, but prevents any sort of collective action for societal good.

Unless you live alone in the woods, alleged individualism is usually a narcissistic or selfish denial of one's true dependence on others for support
