Intersectional feminism is about including women who are structurally disadvantaged or may be discriminated against for other reasons than merely being female.
Poor women, disabled women, immigrant women, women of colour, incarcerated women, women from religious minorities, lesbians. Yes, even women with nonstandard gender identities.
You know who is at the intersection between "female" and "trans"?
Trans men.
Intersectional feminism includes trans men.
It doesn't include trans women because male and female don't intersect.
You are the one who isn't a feminist because feminism isn't supposed to centre male people.
And all those women who are oppressed in other ways, all the groups of women for whom the term "intersectional feminism" was invented have the most to lose from people like you trying to make feminism all about trans women.
Incarcerated women are the ones being locked up with male rapists.
Disabled women are the ones who are at risk of being unable to refuse intimate care from a man who identifies as a woman.
Women from religious minorities are the ones self excluding from women's single sex spaces because they're not single sex anymore.
Lesbians are the ones being told that their same sex attraction is transphobic and that they need to be more open to dating women with penises.
Immigrant women are the ones most at risk of missing out on vital healthcare information because they don't realise that they are a "person with a cervix".
Our feminism is intersectional.
Yours isn't feminism at all.
