It?s always transphobic when a woman or girl doesn?t want to share her safe space, her sports/swimming competition, her prison or her hospital ward with a man. You can?t change sex, however you can get cosmetic surgery to change your appearance and take hormones. This is not changing sex.

Eg Womens Rights Network have groups all over the UK and many local groups in London. https://www.womensrights.network/ @WomensRightsNet on Twitter Don?t bother telling me what I am, I know what I am.
