"JK Rowling faces backlash for comments on the phrase ‘people who menstruate.'"

"... Rowling said she believed that the headline should refer to women instead. Her comment was seen as transphobic, as transgender men can still menstruate."

Twitter reports on a Twitter trend that started here:

She followed up with:
If sex isn’t real, there’s no same-sex attraction. If sex isn’t real, the lived reality of women globally is erased. I know and love trans people, but erasing the concept of sex removes the ability of many to meaningfully discuss their lives. It isn’t hate to speak the truth.

The idea that women like me, who’ve been empathetic to trans people for decades, feeling kinship because they’re vulnerable in the same way as women - ie, to male violence - ‘hate’ trans people because they think sex is real and has lived consequences - is a nonsense.

I respect every trans person’s right to live any way that feels authentic and comfortable to them. I’d march with you if you were discriminated against on the basis of being trans. At the same time, my life has been shaped by being female. I do not believe it’s hateful to say so.
Just because you're empathetic doesn't mean that other people will be empathetic toward you. In fact, they may see you as a mark from whom more empathy can always be demanded. It's like the way they keep giving more work to the busiest person.
