It's because the world in the past it was only right for men to lead due to their physical capability, however, both men and women can be intellectual. The human male is the best *** to be the head since they can protect their family with intellectual and physical prowess. Women would be further disadvantageous once they marry and birth children to continue the bloodline (to procreate = the continuity of life).
Female: Someone has to take care of the younglings and feed them
Male: Someone has to search for ways to keep the family alive and safe.
Now, in the modern era where AI, surrogate *******cy, nannies, and modern medicine and technology have been discovered already, the physical disadvantage of women has finally slowly been compensated by these factors. Thereby, giving them legitimacn taking the lead and being the head of the family.

On a different note, I'm afraid I have to disagree to new or exclusive CR for gays... I don't want to judge, but if did happen... we don't know what could transpire in that small space. Meron nga ganap dadalawa na lang yung CR dadagdagan niyo pa ng pangatlo. And no, that's pushing your luck too far. Genetically, XY *** chromosomes nila so molecularly their males. Likewise, this applies to tomboys and everyone in the LGBTQ community.
Freedom of expression doesn't exempt you from learning proper decorum, etiquette, and good manners.
