This is illustrated by calling Margaret Thatcher an honorary man instead of a masculine woman.
The author is quoting here, he didn’t say that himself:
Josh Hawley, who thinks the left is waging a war on our Masculine Virtues, defines those virtues as “courage, independence, and assertiveness,” presumably qualities that women aren’t meant to have—or if they do possess them, it simply means they’re Manly women (just as Thatcher becomes an honorary man in Mansfield’s formulation)
Society has gone far in expanding women’s possibilities, but the traditional roles for men have not really been changed, so they don’t fit into this new environment. This leads to a lot of confusion, to where we have cis men struggling to perform their gender and looking for help.
I don’t think anybody should ever “perform” a gender! As soon as it becomes a performance, it is unauthentic to the person they truly are, and needs to be deconstructed. The don’t need instructions on how to ‘perform’ a gender, they need instructions on how to free themselves from these expectations.
In this case I would argue that the Author would approach a trans man, who is asking how to be a man
There is nothing a trans man has to do in order to be a man. They are a man. There is nothing that could possibly make them less of a man. No instructions needed. Just be authentic to yourself.
