Gender spectrum is pseudo-science & far-left concept, based on queer theory (queer theory was created by pedophilia supporters).
It fundamentally misunderstands what gender is; it's average biological (sex + neurological sex) differences between men & women. #IAmNonbinary

This is biology 101 but the fact that evolution (and biology) denialism is trendy is telling of state of society
