Post panels of what? Of Oda spelling you out what Zoro's brain processed those days word for word? Do you know what 'show dont tell' means?
That's no fanfiction, it's and interpretation, that you dont like? Fine, however Zoro still clearly has a soft spot for women when it comes to fight, ever since in vol. 1 he saves Nami for Buggy pirates asking them "all of you just for a girl"? And it was later showed multiple other times: Tashigi, Robin, Monet. It doesn't happen once, it is clear that something changed in his way to see things compared to when he was 9 years old, and the death of his superheroine friend is the most logic reason that common sense can give.
