It just seems like the vest way to get rid of toxic masculinity and equality between the genders is to reduce the amount of physiological and biological differences between the genders.

If men and women were sexually monomorphic, then gender equality would be even easier to come by.

At the moment, sexually dimorphism makes men taller, and stronger. If women over time selected for men who exhibited fewer sexually dimorphic traits, then that would be a step in the right path towards men and women being equal.
