Except it's not about sexual organs, because even getting surgery isn't enough to become a "real woman" by her logic.
If you define "real" as in: only a real man and a real woman can reproduce, then I guess there is your limit. That's not transphobic, that's reality.
Maybe not a problem for you, but it is a problem if you were born female. In that case the "the people who were born female" seem to need an action group. But they can't because that would be transphobic.
