Very good aaarrgh, you and the Nazi cucks are trying to use logic.

Gender is both socially constructed and based on biological evidence. This is not so difficult to understand (for others).

Scientific research shows gender is not just a social construct

Evidence that gender has some basis in biology, though, in no way implies a strict gender binary, nor negates the existence of transgender and non-binary identities. Many biology-based gender differences originate from the hormonal environment within the womb, which is very different on average for boys compared to girls. But there’s a huge variation in these environments, says Alice Eagly, psychology professor at Northwestern University. “Within boys there will be a range and within girls there will be a range. To say it’s biological doesn’t mean it’s perfectly binary,” she says.
