"It's not misogynistic to define the category of woman by their biology, just as it's not misandrist to define the category of man by their biology. Women are born with ovaries/uteruses, etc, men are born with penises and testicles, etc."
It is if that's what you exclusively define them as. That's what feminism fought against. We wanted to emphasise our psychological interchangeability.
"In a very small number of cases, you'll get people who are born with disorders that make them intersex, but that doesn't mean that humans are not a sexually dimorphic, sexually binary species - any more than people being born with limb differences or absences chances the fact we're a bipedal species with two arms, two legs, 10 fingers, and so on."
No one is suggesting the sexual reproduction system isn't binary. Rather sex characteristics such as chromosomes, hormones & morphology aren't that combined with genes have the capacity to influence ambiguity in outcomes both physically & psychologically.
"When I think, "What makes me a woman?", I literally can't answer it without resorting to biology. It's not how I dress, my hobbies or interests, or "a feeling". They make up what I am as a person, alongside my biology."
Yes in theory most people imagine reproductive biology. But as I said, in practice they don't & definitions aren't just limited to theoretical views but action.
"I'm a woman because I was born female, which brings with it expectations and problems that society has enforced on women over history."
Not all cis women have the same experiences tho & trans women also have some similar experiences.
