Indeed, this is one of my worst nanoessays. My points:

1) Unjust Privilege of men over women existed in many Societies and continues in some parts of the World.
2) Unjust Class Inequality as described by Marx existed for four millennia.
3) Systems based on Inequality are unviable since the Industrial Revolution. Trying to bring them back is insane.

4) Many Social Justice movements from those who drank wine from Nostrodamus's skull during the French Revolution to those who administered GULAG camps in 1937 to those who view all men as oppressors in 2022 replace Injustice by Greater Injustice.
