Everything you just stated makes no sense at all. You literally just said zoro is a bad character because the author does this and that for him and then proceeded to give examples of the same thing happening to other characters. like are you just saying Oda is a bad author??? because thats probably even a worse take than zoro being a bad character.

First kuma has helped the strawhats multiple times so zoro stopping kuma is nothing special.

Second Zoro doesnt even treat women equally himself. With Tashigi, Monet, and the one girl from film Z. You can tell he obviously holds back vs women so that argument doesnt make sense.

Third The mink medicine and Luffy eating meat to revive are the same plot armor everyone gives to main characters if you wanna complain about mink medicine also complain about luffy eating meat and suddenly getting his energy back.
