If you truly want to speak about the subversive nature of sexism in anime, how in the latest version of the Gundam franchise, Gundam AGE, there is an episode that focused on two supporting female characters that voiced support to the notion that women should give up their dreams, and just let the men in their lives follow their own, we can and should have that conversation. But if by extension you will then illegitimate conversation on how Flit Asuno is an amazing character, making Gundam AGE episodes about him great to watch, then I pity you.
What would be your opinion on Greek classics like the Odyssey? What about the Shakespeare play Taming of the Shrew? Both are incredibly sexist. Other Shakespeare masterpieces like the Merchant of Venice is additionally racist out the ass. But I doubt if in some alternate universe you loved classic books, you'd be writing up an introspective essay on how much you were ashamed of them now.
