>>212142010She is and always has been a radical feminist, who hates men, including men who want to be women a.k.a. a TERF. Before like ~2005, TERFs were the vast majority of radical feminists, however far left viewpoints shifted significantly towards a militant pro-trans stance in the subsequent decades, while she stuck to her original beliefs about men and trannies.
People tried to shame her and then cancel her into bending the knee during the 2010s, but instead she snapped and took a hard and very vocal anti-tranny stance and the left have been obsessed with trying to shut her down ever since.
Hollywood seethes about it in particular, since they hate her, but Harry potter is just too popular and profitable for them to be able to cut her out of showbiz, so they have to overcompensate to feel better about 'compromising' their performative ideology.
