Honestly, I felt it was dunking on Shakespeare a bit - the witches in Macbeth tell him that "Be bloody, bold, and resolute. Laugh to scorn The power of man, for none of woman born Shall harm Macbeth." and the twist is that Macduff was a C-section baby. Which isn't exactly rare anymore. The "I am no man" is the better solution, lol.

Unpopular just means many won't share it, you can still have your wrong opinions.

I have no idea why you would think it's cringe. It's entirely true, and Sauron couldn't tell there was a woman in that armor.
