I read Shrier's book in early August, and can't remember what - if anything - she said in it about feminism, radical or not. Coz her focus really is on the mental health crisis that's occurring amongst girls & young women for many reasons including transmania, how as result they're being sucked into going trans, the dilemmas and damage this is posing for and causing parents and families, and the extent to which pernicious gender ideology has captured major institutions in our society like public education, medicine, psychotherapy and politics. I get the impression that she twigged to what radical feminists have been saying all along rather late in her research. But that might not be correct. I'll have to dig out her book and check.

The other thing about Peterson is - agree or disagree with him, hate or love him - he does have bona fide credentials in his field, he's long been a teacher/professor and clinical psychotherapist, and he has a demonstrated breadth of knowledge in a variety of subject areas. His speaking out about Bill C-16 and compelled speech might have catapulted him to worldwide fame, but before that he had already produced considerable work and put a whole lot of videos on YouTube.

Whereas the author of this book seems to have come out of nowhere.
