This here is the perfect article to bookmark for countering the TERFs and general transphobes who try to use what they learned in middle school biology to claim that trans people either don't exist or to make some distinction between sex and gender, like saying that trans women are "biologically" of the male "sex."

Sex isn’t chromosomes: the story of a century of misconceptions about X & Y

Required reading for all cis feminists and people in general. The sooner we let go of our incorrect notions about chromosomes and gender, the better. And the sooner people get that science is The Ultimate Truth (TM) and changes all the time, the better.

Ah, but there’s a weasel word there: “normal”. And with sex chromosomes, perceptions of “normal” play a huge role – not only in what we think that they are and do, but in the very existence of the term “sex chromosomes”. This is the subject of Sarah Richardson’s revelatory book Sex Itself: The Search for Male and Female in the Human Genome, a history of the science of sex and the invention of the sex chromosome concept – one that Richardson argues we should reject entirely as a mistake that has led to bad science, societal prejudice and widespread misunderstanding of what sex really is.

Seriously, if you're going to talk about science, learn the basics of actual scientific thought.
