Abortion is an issue to anyone with a uterus and ovaries.
I am a genderqueer trans man. My primary identity is that of a male. I am not a woman, but abortion is a relevant issue to me too, because I have a fully functioning uterus and ovaries.
Not all men lack a uterus, and not all women have a uterus either.
Therefore, this issue is not one about gender, it’s about who has the capability to give birth and who has the option of an abortion.
When you say that abortion is solely a women’s issue, you are being terribly cissexist, and erasing trans men who have typical, and functioning, female reproductive organs.
I may be a man, but I have just as much of a say when it comes to abortion, because I am a person who could become pregnant and is able to have an abortion. I am just as included.
Please keep that in mind.
