A name is just a name. Or does she think animals in the wild (nameless) are also genderless?
Not sure about you, but not everyone automatically wants kids, just because they can. I usually respond that I have seen too many alien movies to see something kicking from inside of me as a beautiful thing.
Does she have kids? Karma is a bitch and she should watch her words before she figures out she can't get kids, or gets a handicapped one. Nothing against that but someone talking like her seems like she would find that a bigger deal than usual.
And last.. she aims on hurting you, so don't feel bad to do the same in return. Look at her and figure out her masculine traits, or insecurities (everyone has those especially those who act like a bitch to others). As example (I don't know her) her hands. I would just say something like; You must be really hurting about something. Does it bother you that a biological born male like me has more feminine hands than a biological born female like you? First work on your own insecurities before you find the need to point out the ones of others.
