OK, you still have not explained what feminism is philosophically bankrupt means. I still have no idea. The ideology IS equality - for women but also for men. If you can't define the problems with it in very specific and concrete ways, I'm going to have a hard time taking you seriously on this topic.
My son is a boy because he's got a hairy body, and wears his hair short, and dresses in boy clothes and has male anatomy. I honestly don't see any fundamental difference between he and I beyond that. He's an individual. I'm an individual. We like a lot of the same things and the things that are different have nothing to do with gender. We both have a blend of Yin and Yang traits that are individual to us. I'm not saying this to be contrary or to try to be right here. I honestly don't see it. I'm not saying there is no "spiritual" for lack of a better term difference between us due to gender, but I also see no evidence of that. He has been spared gender indoctrination for the most part because he's oblivious to it, and so what I see is pretty close to what a child looks like absent that sort of "nurture."
He likes dinosaurs but he also likes Barbies - particularly Tour Guide Barbie from Toy Story, which is his favorite movie. He has another favorite one that is a mermaid that he plays with in the pool. He holds hands with males he likes because he doesn't know that "he's not supposed to." And he's also 25 - so that is not a little kid thing. When he was younger, he used to like to put on my high heeled shoes - and we let him without comment. He's sweet and funny and kind and likes animals. He loves his family. That could describe any kid. It could describe me for that matter. He's just a person. His own person, and I love that about him. I don't know what to tell you other than that. 🤷♀️
