- * *Claim*: [brain intersex theory]
- * *Claim*: [transition actually works]
- * *Claim*: [social gender is determined by secondary sex characteristics anyway; you don't usually see someone's genetalia, let alone chromosomes, _&c_.]
- * *Conclusion*: [they actually are of their target gender]
+ * *Claim*: Trans people are born with a brain-restricted intersex condition such that their psychology is much more typical of the other physiological sex: the proverbial "woman trapped in a man's body" (respectively "man ... woman's") trope is basically accurate.
+ * *Claim*: The medical interventions undergone during transition—hormone replacement surgery, sex reassignment surgery, _&c._—are effective at inducing the phenotype of the other physiological sex: physically, transitioning _works_.
+ * *Claim*: Gender is mostly attributed on the basis of apparent secondary sex characteristics: in most situations, most people don't care about predicting the configuration of someone's genitalia at birth or whether they have a Y chromosome.
+ * *Conclusion*: Trans people can legitimately be said to belong to their stated gender, using the _same_ criteria people usually use to decide such things.
