They’re our ancestors. Men, women and children had fireside dinner and chat 300,000 years ago. Women were not asked to sit in separate places. I do not think women were forced to eat less or leftovers.
After 300,000 years, in the 21st century, women are secluded in many parts of the world only because they are women. Not only that, they are forced to eat leftovers and they obviously suffer from malnutrition. Some evolutionary biologists may find logic behind it. I do not find any fucking logic to oppress half of the world’s human population. Sometimes civilization is used to destroy equality.
