You ignoring everything and clinging on those two words is exactly what is causing our problems. Did I claim that trans did not exist in the past ? No, I did not. The prevalence however does NOT suggest that in the past all these people have been oppressed. Is it that controversial to imagine that exposure to endocrine disruptors while in the womb could cause someone to identify as trans later, after more exposure to pollutants ? Does that take anything away from the identity of trans people ? Does that make me "transphobic" ?
