  The Internet has been instrumental in connecting under-represented and
vulnerable groups of people. Platforms built to foster social interaction and
engagement have enabled historically disenfranchised groups to have a voice.
One such vulnerable group is women. In this paper, we explore the diversity in
online women's ideological spaces using a multi-dimensional approach. We
perform a large-scale, data-driven analysis of over 6M Reddit comments and
submissions from 14 subreddits. We elicit a diverse taxonomy of online women's
ideological spaces, ranging from counterparts to the so-called Manosphere to
Gender-Critical Feminism. We then perform content analysis, finding meaningful
differences across topics and communities. Finally, we shed light on two
platforms, ovarit.com and thepinkpill.co, where two toxic communities of online
women's ideological spaces (Gender-Critical Feminism and Femcels) migrated
after their ban on Reddit.
