Where she states about atomozation? In her books her heroes communicate with each other, drinking and go lazy. They can’t communicate with people not their kind, 'cause they get real bored. I doubt you can talk and dance with people you are not interested in.
Yet again, they don’t put themselves above others, they mostly don’t judge at all. They state facts and that’s it, no hostility involved.
All she was rooting for, do what you like, if it respects people right to live. There is no atomatization subtext in her works. If you can provide quotes with explanation, than we can discuss it
Atomization, ie everyone is capable of being entirely separated from society. That’s her subtext, it’s individualistic to the point of absurdity.
