The haters are not ignorant of what she's said and done, but believe, correctly, that it is directly oppositional to TRAs' demands.
Things she's said and done:
She supported Forstater, she mocked language like "people who menstruate", she stated that biological sex is real and important, she drew attention to male violence, she described [gender] as an ideology that is harmful to children, and described the term cisgender as "ideological language signifying belief in the unfalsifiable concept of gender identity." She opposes self-ID, opposed the Scottish Gender Recognition Reform Bill, and donated £70,000 to FWS. She founded a sexual assault crisis centre for women, that excludes transwomen. She opposed the Hate Crime and Public Order (Scotland) Act 2021, and deliberately misgendered several transwomen in order to test it.
TRAs' demands:
Don't do any of this!:

In a country with a state-imposed ideology, she's an agnostic, a secularist, and someone who thinks we should all be free not to believe, and to debate whether the ideology is harmful. One specific harm was the loss of sex-based rights, and she put her money where her mouth is and helped fix it. Exactly this, is what TRAs mean by transphobia.
