"Normal"

What was considered "normal" within a culture has been historically determined based on its prevalence of occurrence. The smaller the percentage of something being observed, the more likely it was that it would be seen as an anomaly or as a disorder. 

Our knowledge of science wasn't very advanced at the time but today it is at its highest point in our history. Suddenly "normal" isn't such a simple thing to determine because nature has shown itself to largely operate on a series of continuums. 

For a human being, at each level of the chromosomes, gonads, endocrine system and the genitals we find possible variations which contradict the concocted idea of a perfect binary. 

Add to that the behavioral aspects of gender (which includes aspects of brain chemistry) and you have a slew of possible combinations for producing a human being who challenges what "normal" is. 

Historically we haven't used science as the ultimate barometer but instead cultural norms which simply decided what was acceptable. Depending on what culture you were born in would determine your social suitability and ability to lead a peaceful life. 

Regretably the western world's Judeo-Christian model was for thousands of years among the most rigid. 

It is now 2026 and when gender criticals say that "sex matters" it makes me chuckle a bit because they aren't basing themselves on our latest scientific reality. They are relying instead on their own determination of what should be permitted based on simplified criteria we espoused decades ago and beyond. 

In that case their 'sex matters" catch phrase loses its potency and becomes meaningless since science isn't on their side.

Instead, they want to go back to an outdated "normal" that has very little to do with the reality of our natural messiness as a species.
