a society that seeks to explore the universe, should be capable understanding that genders are also constructed.
and that between man and women there is interval and even outside of them (superfemale, supermale) exists.

Gender is not constructed. It's biological. There's a thing called chromosomes.
You either have XX or XY.
XX- Female
XY - Male
