A world without gender is a world in which humans are encouraged to develop their full human potential. It’s a world in which characteristics that are considered desirable for humans, such as empathy and assertiveness, are encouraged in everyone, regardless of the form of their genitals—and regardless of whether they have difficulties in acquiring these characteristics because of their genes, hormones, inadequate parental treatment, or socioeconomic conditions. At the same time, children and adults possessing characteristics that are considered undesirable, such as aggressiveness, are helped in overcoming them, regardless of their cause.

A world without gender is a world in which humans are free to fully express their talents in all areas, be it math, poetry—or both; in which humans are treated according to who they are, and not according to the form of their genitals; in which even the thought of grouping them by their genitals sounds as bizarre as grouping people according to the color of their eyes.
