The review was published two years ago in the Guardian, and it begins with this: Some men have for years been trying to deny women the right to their own safe spaces.

Would the Guardian allow that now when there's rather widespread agreement on the progressive left that women should not have single-sex safe spaces?

The deleterious effects of these online misogyny bubbles are enormous. It's now a fact that any ideology, no matter how evil and harmful, gets a support group online where mentally disordered people are told that their untrue beliefs in fact are true and that extreme moves are perfectly fine against the rest of the society.

The incel sites are all like that and so are the other similar ones. And that's how some mass murderers are created.
