It's a disservice to exclude LGBTQAI from biology. We should also work towards being more inclusive and using inclusive language (neutral language, use of medical terminology to describe things versus gendered language; i.e. the word "parent" versus "mother or father"). I'd love to see real in depth information such as the fact that XY chromosomes do NOT automatically make you one way or the other. Many, many factors come into place. Forgoing this information is harmful, inaccurate and promotes erasure of a large portion of the population that do in fact exist.
