Over the last two decades, more and more scientific evidence has mounted to indicate that gender isn't a clear-cut matter of male and female, but rather a more fluid spectrum.
Neuroscientist Baudewijntje Kreukels told Nature that this can be observed in the brain itself, saying, "I don’t think there is something like a male or female brain, but it’s more a continuum."
To provide just one example of such observations, The European Network for the Investigation of Gender Incongruence found that the brains of transgender boys who had recently begun testosterone treatments bore more resemblance to what would traditionally be considered cisgender male brains than cisgender female ones.
But despite increasing agreement among the scientific community and the public at large of this continuum's validity, to say that everyone accepts it would be mischaracterizing the situation. And that reality is showing some serious conseqiences in one Virginia school.
