I have a problem, OP
Thank you for the tips on how to be un-masculine. It's appreciated, and if I ever need to learn more on how NOT to be a man, you're the first person I'll go to.
But your argument is missing a few necessary pieces.
>Masculinity is a social construct
>Masculinity has created a society in which men dominate completely over women
>Therefore masculinity must be gotten rid of to achieve true equality
I, too, believe masculinity is a social construct.
I, too, believe masculinity favors men for more dominant roles
I, too, believe that if we didn't recognize masculinity and femininity we would have (gender) equality
But is that something we ought to do?
Could it be good for society to have such constructs in place?
Could it be a necessary evil?
Every society in the world is hetero-normative.
Every society in the world affirms masculine and feminine social constructs (even though some attributes of each change from culture to culture).
You can find places in the world where men and women are considered equal.
But there are very few, if any, which consider them, and the usual roles they play in society, exactly the same.
Those are just some facts
But why are there only societies which include such social constructs?
Either
A) These constructs are not biological in nature, and were created artificially. Somehow they helped (or at least didn't harm) society, and persist to this day, whereas those who did not have these constructs (if any) did not survive, indicating that societies with these artificial constructs operate better for them, or at least operate better than they would without them
OR
B) These constructs are in fact biological, or related in some way to biology, and therefore all societies, from the Iroquois to the Babylonians, had such social constructs; it was inevitable, because they are part of human nature, rooted in our DNA.
