From the Spectator article:
Associating gender-critical feminists with men who have abhorrent views is a favourite trick of trans activists, and Pesutto’s lawyer did his best to enforce the improbable link with reference to Moira’s views about Victoria’s ‘safe schools’ programs. Deeming has been an outspoken critic of ‘Safe Schools’ type programs, and on cross-examination, made it clear that she wouldn’t easily be tripped up on articulating her motivation for that opposition.
Deeming, and all women’s rights activists on the gender critical side, oppose ideological sex education programs like ‘Safe Schools’ because, in their view, they violate long-standing children safeguarding principles. Failures in safeguarding will make children vulnerable to paedophiles, but this has nothing to do with gay and lesbian people, just bad policy.
I remember the Australian "safe schools" programmes from a while back. They were created by queer theorists and based on queer theory. They were badged as "anti bullying" a tactic also used here, when they were more about gender identity ideology.
