A lot said here that I could agree with, not sure what else I could add to this conversation, except my two cents:
Swapping genders and race? Again, really depends on how it's done, but my first question is always, WHY? Why, is there a particular need for this besides the usual risk of just pandering to a group? That's why I think ironically the SJW's have poisoned the damn well so much, so that if someone for any reason other than NOT pandering to a group does decide to do a race or gender swap, they'll get accused of said pandering anyway.
My personal Golden Rule: PUT THE STORY AND CHARACTERS FIRST. Put the gender and race crap to the very back of your damn brain when writing a story, and if someone happens to be black, Asian, gay, bi, or whatever, oh hey great, but it should hardly be noticeable as it's the CHARACTER that shines through first and foremost. I dare anyone to look at a movie or book that's made now where they force race or sexuality or gender swaps on characters, and I will bet you'll find the movie or book is suffering for it because it's choking the muse, the story suffers for it at the cost of ridiculous politics. It happened with state-sanctioned "art" under the regimes like the Nazis and Soviets, though admittedly there were exceptions here and there.
Speaking of sexuality...I never really went for the sexuality angle swap on Willow, that felt forced and silly and meant more to appeal to the "controversy sells" crowd (Lesbian-Gay-Bisexual was in a different playing field in the 90s). Personally, I would have went for a bisexual "coming out" with Willow that would have made more sense, plus it would have led to a very interesting relationship with Willow and Xander if Willow also decided to pursue a female romance with someone as well...how scandalous. 😉 And I'm sure Xander being the horndog as he was would not at all have disapproved whatsoever especially if said "other woman" was also bisexual and was also interested in Xander, and this is an idea I hope to pursue in a BTVS fanfic, but that's for a different thread..."cough".
As for what Spartan303 mentioned, Gotham High? I thought that was just a parody comic...until I saw a few panels myself. Holy crap, that's just....no, NO NO NO NO NO NO NO. I'm not as avid or fanatic a comic reader as some, but that's just godawful. 🤢🤮
