You come off as a troll, but in case others are wondering:

She has, she's the loudest voice of the anti-trans movement. Here in the UK it led to the murder of a trans teenager (Brianna Ghey) and an attack on a literal toddler by teenagers over the fact the victim had a trans parent. But it's not just direct violence either but political violence also.

Thanks to JKR, not only is anti-trans bigotry now getting similar protections to religion in court (Forstater case) which rendered workplace protections against bigotry and harassment for trans people moot, but we are seeing mass rollbacks of trans rights gained in the past 20+ years such as (but not limited to): ban on puberty blockers for minors, bans of trans women from women's hospital wards, bans on discussing the existence of trans people in schools to children under 13, guidance to schools by the government suggesting trans children in unsafe home environments should be outed to their parents and a crackdown on DIY hormone suppliers etc.

In addition proposals include scrapping the 2010 Equality Act's protections on gender identity and/or the 2004 Gender Recognition Act (or making the latter meaningless), as well as bans or restrictions on medical transition for adults under 25 and suggestions in not only keeping legal but encouraging conversion therapy for trans people amongst many others.

This all against a backdrop of what already was a very hostile environment for trans people 8 years ago when all this started with the right-wing shift, which has now only gotten worse as systemic neglect led to institutional traps of inaccessibility in the UK trans healthcare system that has resulted in several high-profile deaths just in the past two years, all because trans voices have been institutionally silenced in the UK both in the media and government, neither major party or any major media outlet support trans rights etc.

From her direct harassment of trans people (e.g. India Willoughby) to her rhetoric projected to millions comparing trans women to rapists or more recently house burglars, her denial of the fact trans people were targets of the Nazi war crimes, her spreading of misinformation regarding trans healthcare (more recently - who invented it) normalising anti-trans hate to her significant capital backing of the TERF movement which has successfully captured the media and all major political parties in the UK and would be nowhere near as successful without her support - she may not be alone responsible, but she is very much complicit.

There was a moment when my generation of trans people may have been the last to be severely marginalized, in comparison now thanks to her and her pals influence people transitioning today have it much, much worse than those of us who did it 10 years ago.

So when trans people froth at the mouth about punching TERFs, you know why now.

As someone who knows many who are personally affected by this, I believe that If we lived in a world with anything resembling justice, JKR would be paying reparations for the rest of her life for the lives and youths she's complicit in ruining forever.
