I don’t see where I’ve conflated anything, nor do I understand your attempt to show where I have. “Biological sex” is redundant; sex is a biological classification. There isn’t any other kind.
You argue that people who are intersex regularly identify as male or female, and do not like being pointed to as trans representation...but that's not describing their biological sex characteristics, that's describing their gender identity. You're describing someone who identifies as cis-male or cis-female, despite their biological sex characteristics.
