Siouxrose, you would fail a biology course. All domesticated plant and animal species are genetically-modified organisms. The only way to avoid genetically-modified organisms would be to go back to being hunters and gatherers. Wild game and wild plant species are not genetically modified. If you have a dog, you have a genetically-modified wolf.
Our ancestors were hunters and gatherers, meaning they had to eat meat to survive (you can't survive on a diet composed only of wild plants). All humans have taste receptors for cooked meat. If eating meat were bad for humans, those taste receptors would have been eliminated from the population by natural selection.
Patriarchy evolved with the invention of agriculture and is several thousand years older than capitalism. When humans discovered they could domesticate plant species and herd domesticated herbivores, life was much better. Instead of the males chasing wild game and the females gathering wild plants (nursing females and the presence of small children would hinder a woman on the hunt), growing crops and having animals present as a food source allowed our ancestors to become sedentary. Since the food supply was constant (hunters and gatherers live by feast or famine), the human population grew rapidly (compare the population of native hunters and gatherers on the Great Plains with the population in Europe at the same time. The natives on the Great Plains never did domesticate anything as a food source, they simply followed the bison.
Agriculture requires land. So humans came up with the idea of private property (owning land; hunters and gatherers have no concept of owning the land). Females stopped contributing to the food supply and became the property of males and a source of children who would work the patriarch's land and inherit it when the patriarch died. War was invented to take land from a neighboring patriarch who was not as strong as you. Eventually, one strong patriarch controlled a large amount of land and you had kingdoms. One really super-patriarch would control an empire (think of Caesar and the Roman Empire).
The only way you will abolish patriarchy (male dominance) in society would be to go back to hunting and gathering (gender equity was part of hunter and gatherer societies because females contributed equally to the food supply). But if you go back to hunting and gathering, you will have to eat meat because it is impossible to collect enough wild plant species to survive.
You might be able to convince people to eat only domesticated plant species (only rich societies can afford to grow crops to feed animals so that they can eat meat), but this would not solve the problem of patriarchy because the status of a patriarch is determined by how much land he owns.
Both the Torah and Aristotle state that male dominance of females is natural and Aristotle also claimed that Greek males are superior to barbarians. Because barbarians are inferior, it is right that they should be slaves, argued Aristotle.. This is because both the Greeks and the ancient Israelites were agrarian societies and this is why patriarchy was thought of as natural. Just as hunters and gatherers have no concept of owning land and subjugating women, agrarian patriarchal societies think that slavery and subjugation of women is natural.
You like to bash capitalism, but we know that when a society industrializes and emancipates women, the population growth rate slows down (demographic transition; Japan actually has a negative growth rate). It is not a coincidence that when the US was an agrarian nation of yeoman farmers, women didn't have the vote. It was only after the US became an industrial giant that women got the vote. Since the Industrial Revolution produced capitalism and also allowed women to become emancipated, I would think you would be in favor of capitalism.
Calls for social justice happened long before the Industrial Revolution. The Old Testament prophets railed against the oppression of the poor by the rich. Early Christians were communists. "All whose faith had drawn them together held everything in common: they would sell their property and possessions and make a general distribution as the need of each required." (Acts 2: 44-45)
