ah, perhaps "influential" is not the best word choice on my part - I guess what I meant by that was not most famous or reaching the most people, but rather the most successful in their anti-trans advocacy, i.e. Rowling hasn't had the same kind of influence on trans rights as other anti-trans activists like Matt Walsh, and even Posie Parker I would argue has been more successful at achieving goals of the anti-trans movement than Rowling. Rowling is more famous as a transphobe and in that sense I agree with you she has a bigger platform and can bring more people into the anti-trans movement.
