Masculinity is a social construct.I would argue masculinity as a concept should be abolished.The same goes for feminity.There is no way to define masculinity without it sounding demeaning to women(and men).If masculinity means being strong,courageous and intelligent then if a woman has those traits does that make her masculine? If femininity means being kind,caring and compassionate then if man has those traits does that make him feminine and is that a bad thing?There is no non-biological difference between men and women.Heck I would argue there is not much biological difference either considering trans and intersex people also exist.Biologically a person can be born with XY chromosome and still be ciswoman and a person can have XX chromosome and still be a cismen.Considering all of the factors above both masculinity and feminity as a concept should cease to exist
