I don't think it's accurate to do this sort of either/or pigeonholing either way, or to try to make the case that women can & should be divided into two camps depending on whether or not we've had children.

Yes, a lot of women who are vocally & actively "GC" don't have children and would call themselves radical feminists.

But many of the women who have put their heads above the parapet - and their jobs, reputations and livelihoods on the line - to raise the alarm about the dangers of the trans movement, and who've taken direct action to combat it, are women with children. For many women with children, there's a double motivation behind opposing the trans craze: they/we are concerned with girls & women's rights, and also with the safeguarding of the young & vulnerable of both sexes (including boys who are being transed by their parents like Jazz Jennings & Jackie Green, as well as boys who've been punished for not toeing the line of trans ideology, such as the one in Scotland who got expelled from school after recording his teacher say he wasn't allowed to claim that there are two sexes, & the young autistic man in England who was tried & convicted of a hate crime for asking a young TIF police officer, "are you a boy or a girl?")

A lot of enormously effective work countering trans ideology and politics has been done by mother-led parents groups like Transgender Trend, 4th Wave Now, Safe Schools Alliance. And by individual women who indeed do have children such as Lily Maynard, Abigail Shrier, Sharron Davies, Martina Navratilova, Beth Seltzer (founder of Save Women's Sports), Posie Parker/Kellie-Jay Keen, Maya Forstater and many more, including of course JK Rowling.

Also, a lot of women actively involved in trying to stop the trans train, including some whose names I've mentioned, don't call themselves "radical feminists" - or feminists at all. Some are "old school" feminists (like me) who came of age during the second-wave; because today's liberal feminism wasn't a thing back then, most of us just called ourselves plain feminists - adding the radical to mean root wasn't necessary, and having to do it today feels a bit strange. Still others are women who used to call themselves feminists but now eschew the label - like Posie Parker/Kellie-Jay Keen.

At the same time, many women who are vocally and actively fighting the trans tyranny and gender ideology have never been feminists, radical or liberal, nor are they now: politically, they are conservatives, centrists, moderates, libertarians, and so on. In the UK, conservative women like Tory MP Jackie Doyle Price, former left-winger & now conservative writer/columnist Melanie Phillips, and religiously conservative international women's & human rights champion Baroness Emma Nicholson of the House of Lords have stood up to oppose trans tyranny, as have some conservative female pols in Australia - and a number of Republican women state legislators in the US.

Some of the most vocal and bright women standing up in the public sphere to openly, adamantly and most effectively speak out in opposition to trans ideology and tyranny are most concerned with the censoriousness and authoritarianism of the trans movement and its attempts to shut down free speech with its "No Debate!" mantra. Like Lionel Shriver. She is extremely outspoken on this topic, and super-smart, but I dunno whether or not she has kids, nor would I assume she'd consider herself - or others would consider her - a radical feminist. (I suspect not.)
