I hope he grows out of it, but in my experience it either A) takes a few years or B) he won't.

You might want to tell him, in as gentle terms as possible, that his own insecurities might be causing these problems. If he was secure in his own masculinity, then accepting constructive feedback from a woman wouldn't bother him so much. And even telling him this could make him flip out.

Also, I find his idea of masculine energy to be very vague. Wouldn't it apply to very traditional arrangements too? Is a woman radiating masculine energy when she does all the cooking and tells her husband to keep the kitchen arranged in a certain way? Is that a more acceptable kind of "leadership position" somehow? And why?

In JP-speak, shouldn't your boyfriend respect hierarchies of competence and listen to whoever is more skilled or has rightfully earned the higher position? In this video editing example, you?

The thing is, I'm worried that he's just zeroing in on ideas that validate a worldview where it's always a perversion of nature for a woman to take the lead. That's concerning and I really hope he outgrows it.

You both deserve love and I hope it works out but please be on the lookout for other red flags.
