We all know Mumsnet was started for mums. It is clear that the main people attacking Mumsnet over this are not genuine Mumsnet users, but angry (male) social justice warriors seeking out supposedly transphobic comments. Their response is then to attack Mumsnet and try to deter advertisers. Their actions show contempt for women and complete disregard for the wonderful tool that Mumsnet is for countless women, including those who are vulnerable and/or struggling.
I am happy to agree that some of the terminology used against trans people has been abusive and unnecessary. But most of the trans discussions simply state fact (such as acknowledging biological differences between women and transwomen) and share valid concerns about the impact of the GRA on women's spaces, women's sports, women's health, etc. By health I refer to recent attempts by transactivists to ban the words "mothers" and "women" from maternity care.
What's the priority here? Providing networking and support for mums or validating the identity of angry social justice warriors? I don't know how anyone who wants to shut down a forum for mums can possibly claim to care about women, let alone be one.
