Actually it does mean that. Teaching self defense unless he's literally just going to sit and watch (which helps no one) means he has to practice with a female Sanji. It also means he has to approve of a female Sanji fighting. The way canon Sanji has interpreted Zeff's form of chivalry has shown that Zeff is VERY old fashion not just your grandparents old fashion. I was being generous in saying he'd even adopt a female Sanji. He probably wouldn't. Sanji proved himself by attacking Zeff, Zeff wouldn't have kicked him for it, thus he wouldn't have crawled, bit him and professed his dream. Zeff would have just ignored a female child Sanji and his crew toss 'her' out to the rest of the Orbit's crew. Giving nowhere for Sanji to even mention 'her' dream.
In that scenario if they did somehow make it to the rock and survive, he's the type to just become over protective and not let a female Sanji fight. May teach her cooking, but not employ her as he literally stated to canon Sanji he does not employ girls. Changing Sanji to girl would be changing all of Zeff's own values.
And no, changing chivalry doesn't work. Chivalry was a code of honor for men to treat women. There is no reverse form and no womens version for other women because women are already expected to treat other women nicely. There's just no point at that point.
A girl is expected to show care an emotion, even Reiju showed it around her mother, and despite being strict Judge never had it beat out of her. He may be disappointed in a Female Sanji showing care and emotion but it won't escalate to a dungeon and disownment.
That would be forcing a character into something they don't want. This was written in the sense where people make Sanji a girl and try to keep everything in his story. His story made it clear he doesn't want it. Changing him to want it, ditches his personality.
We already get that in Nami. You don't need to take Sanji away from the boys just to give the girls another icon and to please fetishists.
Considering you replied this to my last point. You're basically saying you think changes that validate harassing and forcing people into things would be an interesting change. -- So we're done, I'm no longer replying to you after this post.
Let me put it this way.
If a character was raped (let's say Ginny) would you suddenly say the character is in denial and actually wanted it, or give her time and she'd want it?
No?
That's the same thing you're saying by saying Sanji who was Harassed, Chased, Jumped, Forced, and Anime Brainwashed is just in denial or given time will change to want it.
That's sick bro.
