Then why educate this girl from an early age?
Because of the patriarchal society, boys have great advantages in all aspects, including objective physical strength. If absolute equality is advocated, then women have almost no opportunities in some fields, which will lead to actual inequality.
For example, if the bus does not advocate respecting the old and loving the young, everyone will be equal. In this way, the seats are more easily occupied by young people who are agile and have physical advantages. Young and middle-aged people may stand for more than ten minutes, but the elderly may faint. People who need seats can't grab seats, and people who don't need seats can often grab a lot of seats. This leads to the phenomenon of actual inequality. Therefore, respecting the old and loving the young does not mean that the old are stronger, but that the old are weaker than the young.
Similarly, the priority we advocate for women actually reflects that women are the weak side in society. If we don't take care of them, the balance will be unequal. Then girls may not have any chance. Girls are more likely to be injured in earthquakes because boys are in better health. Girls are more likely to be bullied when fighting, so everyone defaults not to hit girls. This is the social protection for the vulnerable groups.
Even so, men and women are still not completely equal. Nowadays, women still encounter many unfair treatments in education, job opportunities, promotion opportunities and gender discrimination. There is still a long way to go to achieve gender equality.
We don't advocate complete zz correctness, and civilized society pays more attention to everyone's rights. I hope everyone can establish the concept of equality and respect everyone from the bottom of my heart, no matter whether she is a man or a woman.
