Why cannot trans women be content to be simply - trans women. Given the same respect as any other human being. With or without surgery or hormone treatment, beards, penis. Wearing a dress if they feel like it, or joggers, leggings or even a grass skirt if the mood takes them.
But allow that XX and XY is the ultimate arbiter of biological sex. And that in certain settings - all described many times on GN, women do not want to share the same space... for reasons also outlined many times also.
Trans women and women share various interests - I'm sure. But our lived experiences will be different.
TW, with full male genitalia who insist they are women are, IMO, practising another form of misogyny - by defining womanhood - to their advantage. And it gives them power over women which they wouldn't otherwise have.
NO, a woman cannot have a penis.
