Those are birth defects; not biological variances.
"Birth defects" ARE biological variances.
People born blind, with 2 fingers on each hand instead of 5, females without fallopian tubes; these are examples of something going wrong. These are not like variances in estrogen levels or different melanin levels. I never called birth defects/anomalies; biological variances.
As I have said before, multiple times now since you somehow don't seem to get it yet,
the point is that these things do not preclude a person from belonging within certain categories. The fact that the majority of human beings are born with sight, or five fingers, or biological women have fallopian tubes, does NOT MEAN that those born WITHOUT sight, five fingers, or fallopian tubes are NOT humans or women. The point is that these biological categories are NOT DEPENDENT on very specific features or traits, because the various traits associated with those categories are VARIABLE.
If I’ve known you for a while, and one day you claim to be a girl, I don’t have to sexually assault you in order to realize your biology has not changed over night.
Correct. You would have to have sexually assaulted me both before and after, since you would be presuming I was a particular biological sex to begin with.
The exceptions are people born with birth defects and medical conditions. These are not the people claiming gender issues; people claiming gender issues are almost always people born physically whole.
We were talking about biological gender and how we classify it. The point is that these medical conditions DO NOT PREVENT A PERSON FROM BEING CLASSIFIED AS A CERTAIN BIOLOGICAL GENDER, so to say that being biologically male and/or biologically female is dependent on any one or a number of these features is false.
That's the point.
If gender were purely social,
It is, by definition.
you wouldn’t have trans people trying to look opposite of their sex.
No, they're trying to look like a particular GENDER. Once again, "looking like their sex" would be a misnomer to you, because - according to your definition - your sex is entirely related to biological characteristics. I'm not sure how a person can "look" like they have a vagina, or fallopian tubes. I'm not sure if you're aware, but you don't need XX chromosomes to wear a dress and makeup. These things are SOCIAL PRESCRIPTIONS, not biological ones.
Why are biological males having their sex organs replaced if female sex organs has nothing to do with being a woman?
Again, see above. It's about the expectation society has, and because - for a lot of people - they find it difficult to see you as a woman if you don't "look like" one or possess a penis.
Their actions speak louder than your words.
You don't seem to understand their actions very much.
