Gender Rant

There is a serious issue with the way this guy approaches this subject. For one, he doesn’t identify, or at least, recognize, a difference between sex, natal gender and gender.
Sex or “Basic Biology” as he calls it, is defined by chromosomal arrangement, gonads, genitals and sex hormones that we are born with. We use those categories to distinguish what sex a child is, and as a society typically fall into a problematic binary. This binary of male and female is so problematic because there are also Intersex people, whose chromosomes, gonads, genitals and sex hormones defy the typical definitions of male and female bodies. These people who are intersex defy the binary, because there is an ambiguity to some of these characteristics that everyone possesses, these ambiguities often involve but are not limited to: genital ambiguity, as well as differences in chromosomal genotypes and sexual phenotypes of a single person (The typical XY/XX situation).
Natal Gender refers to the typical Boy/Girl assignment that most doctors give upon the birth of the child, and this assignment is typically given because of primary sex characteristics, namely if you have a penis or vagnia. Intersex people usually don’t do too well here, as often their sometimes ambiguous genitals are shortened/cut off/lengthened to fit whatever sex the Doctor “judges” the child to be, and it is a gross and serious issue.
Gender, however is a spectrum of characteristics that belong to a certain variety of cultural roles, note there, that gender belongs to culture, and not biology. Gender is derived from a combination of factors that are assigned to typical boy/girl roles and everything inbetween. That is to say, someone may find themselves comfortable in a role that is somewhere in between traditionally masculine and feminine, on either extreme, literally anywhere in between the two or a role nonconforming to, or that does not fit on our traditionally Masculine to Feminine based spectrum. Gender is a SOCIAL identity that begins developing because of many factors some even before birth, these factors include but again are not limited too: Gonads, Natal Gender, Sex, Hormones, Social Environment, Body and Brain Chemistry, and many more.
This conversation is an especially bad example of an inexperienced speaker who means well, debating with a person who knows how to win an argument without being technically right. It is not as simple as “a boy who thinks he is a girl, or a girl who thinks she is a boy”, and the idea that these people all have Gender Dysphoria is incorrect, the diagnostic criteria for Gender Dysphoria includes “Clinically significant distress or impairment in social, occupational, or other important areas of functioning due to a marked incongruence between one’s experience/expressed gender and assigned gender (natal gender), of at least six months duration.” (Source: DSM 5, APA)That is to say, there must in fact be a distinct distress that causes an issue in the social lives of those affected, to the point of impairment. Not all trans people have this distress, or are impaired. For whatever the reason, not all Trans people are therefore Gender Dysphoric, and as such his usage of this disorder as a means to qualify all Trans people as mentally sick or disordered, is inappropriate of him at best.
