Gaea certainly is.

I learned from Jurassic Park that females are default since they're XX and males are XY, but it turns out that's just specific to humans, and its reversed in some animals, where others determine sex not based on genes at all.

And Adonai had a consort, Asherah that was actively removed and censored because her culture was dominating.

Those weirdos, I thought everyone knew by now that she's Alanis Morrisette

Maybe ask them to explain Gen 1:27: "So God created mankind in his own image, in the image of God he created them; male and female he created them."

He's just as much female as he is male, and vice versa. "He/Father" appeals to a patriarchal society, but Jesus had a good proportion of female followers, and it was some of them that discovered the empty tomb. God is neither male nor female, or both, depending how you look at it.
