They are men becoming a man’s idea of what it is to be a woman.
Miranda, you nailed it. THIS very sentence is exactly what I've been trying to explain to my husband.
My mom is 6 feet tall, has huge hands and feet, a relatively deep voice (beautiful alto), and doesn't wear makeup. She likes her hair short, doesn't color it, and prefers comfortable clothing and shoes, (flannel, cotton, sneakers). She loves fixing things herself, and still chops and hauls wood for her fireplace. She is the original gender nonconformist--she just does what she wants, and really doesn't care what anyone else thinks.
But make no mistake that she is ALL woman. She birthed three babies, nursed them, suffered years of endometriosis before she finally got a physician to agree to a hysterectomy. She has dealt with the challenges of a "woman's profession" (nursing), and is still processing the guilt and shame instilled in her from her own strongly Catholic upbringing.
And despite all this, (just in recent years), she gets asked about her pronouns. As if because she isn't plastered with makeup and pearls, her femininity is in question.
