I agree with most of this. Good man or good woman is a declaring of character. However, biologically it is difficult for men to overcome the phenomenon of paternal uncertainty. Since maternal uncertainty does not exist, men inherently are plagued with this Byzantine generals problem with regards to fidelity and the potential that they may be raising another man’s offspring. This is where I think the character of a true masculine man is tested. It is quite the societal conundrum, but communicating the nuance is important so society does not skew too far toward toxic masculinity or it’s polar opposite toxic femininity
