I think the invention of "non-binary" has been one of the more destructive things to come out of the new gender movement. It solidifies the idea that if you don't "feel" like a man or a woman (ie: identify with stereotypes), then you are in fact not a real man or woman and should call yourself something else instead.

"Non-binary" is not just a harmless identity or phase that involves pronoun changes and haircuts. For many young people, it's a gateway to a more solidified transgender self. And many people who identify as non-binary do go on to take hormone and have surgeries, despite in many cases experiencing no bodily distress. They insist on denying the reality of biological sex and instead claim that they are magically sexless beings based on the way they feel about being male or female. As a GNC woman who happens to dislike being female, I find non-binary claims illogical and occasionally even offensive. It almost feels like female non-binary people in particular just think they're better than the rest of the female population.
