In response to the JK Rowlings Twitter furor: I do not define myself by my menstrual cycle. That is why I am a feminist. I will not call myself a ‘menstruater’ or a ‘person who menstruates’, especially since I am long-since postmenopausal. I will continue to proudly call myself a woman. That is not going to change & it is not transphobic to do so. Feminism taught women a pride which had been deprived to centuries of women. There is no going back to oblivion.
