It's almost like people are looking for a reason to talk about how much they hate JKR, and in turn promote her.
The Streisand effect is in full display here.
Everytime people bring out the three minute hate drum, the righteous come around and sneer, so there is a echo chamber, but there's always somebody new, somebody who's never been introduced to the debate before, who now pays attention to this person... And they might end up agreeing with this person.
So giving all this attention to one person over and over again, is creating them more converts than it's costing them. It's just promoting the personality at this point. It'd be more effective to ignore them, and just promote your own viewpoint. There wouldn't be any controversy, there wouldn't be free media attention....
Because she has asserted the right to spaces for biological women only, such as domestic abuse shelters and sex-segregated prisons. Because she has insisted that when it comes to determining a person’s legal gender status, self-declared gender identity is insufficient. Because she has expressed skepticism about phrases like “people who menstruate” in reference to biological women.
Her take isn't crazy - it's not supportive, but not phobic either, and she clearly enjoys the media attention and public debate. She thrives in it.. so she wins everytime people give her attention
Ignoring bigots only encourages more bigotry. She needs to be called out on her bullshit each and every time. Whether or not it has any effect on her isn't the point - it shows others that such behavior is not acceptable.
