The "womanosphere" sounds very much like a label invented by bitter leftists, not a self assigned label.

They've literally just thrown Candace Owens and a women's magazine about homesteading into the same basket for the crime of having a different opinion to a typical NPC lefty.

Do you know anyone who goes around claiming to be part of the "womanosphere"? Nope? Neither do I. But I know several hundred lefties who parrot the opinions put forward in this article because they're unable to think for themselves.
