How would you argue against "females are "superior" to males because all embryos start as females, the female sex came before the male sex in evolution, and males evolved later from females" that misandrists bring up?

I have recently found a user claiming the following on private messages;

User: "Here are some reasons that females are "superior" to males:

1) The default sex of all embryos is female. Female is the default sex of all embryos and all embryos start as females, and if no SRY gene is activated on the Y chromosome, all mammal embryos will BY DEFAULT continue on as females.
2) The Mitochondrial Eve is 200,000 years old from East Africa, the Genetic Adam is only 60,000 years old, from the same region. The female genotype is homologous XX, the male is a deletion mutation of one of the Xs to become a much shorter Y chromosome, later in evolution. Y chromosome evolved from X chromosome. That's why the female sex came before the male sex, and females were the original genotype, and males evolved later from females."

How would you argue against what this user said?
