to be honest, nothing has really changed about victim shaming and sexism on modern days manga. i remember very cringy things on Bakuman about how "girls should behave" ( member girl, if you have good grades and are proud of it, you actually are stupid because good girl are humble and don"t brag'' ) and how the mother's protagonist ''can't understant what is like to have a dream for a man'' because you know; she is just a housewife, she just can't get it.
and don't get me started on countless shoujo manga where sexual arrasment and attempted rape is okay because the girl will eventually fall for the boy.
