I can see them going after JKR more than Musk, from this. She's a woman who stands up for women's rights under an extremely misogynistic government. Musk is a man under a government no less misogynistic, but with the whole freedom of speech background.
Are we to believe the "raised as a woman and thinks he is one" claims about IK? Frankly I don't believe anything coming from his supporters. Altitude chromosomes, etc.
