Gender is the distinction between men and women. If you eliminate the distinction, which feminism is trying to do as quickly as possible (along with LGBTQFHTKEO), you eliminate the concept of gender alltogether.
The former can be achieved without the latter - just jail people who dare to discriminate against women, problem solved. Soviets managed to implement this even in Muslim states, go figure.
The latter is how the former is being attempted in the West and some are skeptical.
Men and women are different. Women have decided that they don't want to be women any more. The results have been disastrous. Families are falling apart today. 60% of people in prison come from home without dad. We have more money than ever, and less happiness. People are so silly. They confuse money and power with happiness. Incidentally all the divorce that comes thanks to women actually leads to more poverty. (2/3 of divorces among college educated come from women)
Most people have been thoroughly brainwashed. There are only a rare few like Neo who the programming just doesn't quite work for.
