1) Nature at all levels is replete with anomalies and permutations without exception
2) The human process of procreation and giving birth forms part of nature's biological mechanisms.
3) 95% of males and females conceived through this process align their gender identity with their birth sex which means that gender identity is influenced by biology (and only later attempted to be influenced through socialization)For proof of this see case of David Reimer.
4) This biological process is independent of race, religion or culture and is universal hence always predictable
5) Therefore anyone whose gender identity does not align with their birth sex must have had that identity partially or fully impacted by that biological process since transgender people are, in the vast majority of cases, highly functioning and not mentally ill.
What this means is that anyone who states that being transgender is part of a sociological movement isn’t thinking straight or, as is more commonly the case, blinded by personal belief.
Hence it follows logically that it wasn’t your decision to be born transgender. You simply were and the only thing left for you is to decide how to cope with that reality.
