Bitch aint even really anti-troon. She just supports women shelters that don't accept troons as there's a precedent of troons raping women in shelters. Other than that very minor, technical aspect, Rowling is lefty as fuck - for example, for a theater adaptation about a decade ago, she had a hand in casting a nog as Hermione, and defended her choice loudly on twitter. Not to mention there's a troon in her game that is not treated as a troon, but as a woman, for normalization purposes.
But troons are high on estrogen, and thus their mental capacity is as low as a woman's. Of a schizophrenic woman. So if you only comply 99% with their delusion, they'll try to ruin your life and the life of those that support you even in the most tangential way, because that missing 1% of your support makes you literally a nazi.
