I don't think I'm exactly right about this, but consider three sets of words: - man/woman - male/female - masculine/feminine There is a concept of grammatical gender, where words can be masculine or feminine (or neuter in some cases, and there are other systems as well with different words). You don't talk about man words or male words, it's masculine. So, I tend to think of gender as masculine or feminine. That covers most people (although not all: nonbinary, gender fluid, genderqueer, etc. are all real). I tend to think of sex as male or female. At least for human beings, that covers most people (not all, intersex is a real thing, and there are other unusual but 'natural' configurations as well) So one way to look at this - which again, is probably not exactly correct, but it's how I think - male/masculine and female/feminine are what we've traditionally thought of as man and woman. But, I think it's pretty clear now that we need to account for the other combinations, i.e. male/feminine and female/masculine. That's where cis- and trans- come in: male/masculine is a cis male, female/masculine is a trans male, both are subsets in the set of all men. Same with women. We've got nonbinary, genderqueer, etc. as well. I don't really understand the latter, but the former is pretty easy to explain: imagine being told you had to be masculine or feminine, and your response was "No, I don't. I prefer or reject some of each." Overall, to me, gender is about what you like and how you behave, while sex is more biology (i.e., what's in your pants). It's easier to understand the arguments if you completely separate gender from sex, and don't make assumptions about one based on the other. In fact, I think the assumptions - e.g. gender roles - are the entire problem, and if people would just stop with that, a lot of things would get better.
