I don’t think she did help create the worldview. She’s just a “post-Christian” humanist - whose books always relied on the basic Judeo-Christian division between good and evil, even though she denied its source - who was too naive to realize that cutting loose from the moorings meant that anything could grab your little boat and smash it.
Like most of the British intellectual class, she’s ravingly anti-American and particularly anti-Trump, but the left has gone full-bore anti-reality ideologically bonkers, so even her past wasn’t enough to save her. I hope some of her fellows at least pause to give thought to the implications of this.
