Don't cite Wikipedia as a source, did your teacher never tell you that?
I'm not sure what's the point you are trying to make. Do you know why teachers tell you to not cite Wikipedia? Because it's an encyclopedia, it's not a primary source. You cannot use secondary sources in school assignments. This isn't a school assignment, I'm showing you the definition of something for your own reference. If you were making an actual assignment, you'd have to consult the extensive bibliography that the wikipedia page provides and write it from there.
Gender bending, as far as the fandom has always been concerned and always will be, is the act of a a person of one biological sex being magically changed into the opposite biological sex either via magical change or body swapping. That's it. Nothing else falls under the gender bender tag, certainly nothing to do with traps or crossdressing and trans is never gender bender.
I already explained this here, taggers are moved away from the term genderbender for a reason. Danbooru doesn't use it, neither does mangadex, and this change isn't recent either. You are describing a gender change, not a bend, and your dogmatic stance clashes with it because it's completely outdated and inaccurate.
Take two men. One of them gets hit with a "turn into a girl magic spell", the other gets hormone therapy and surgery etc. The first one was genderbent, the second one is trans.
The two of them proceed to live out the rest of their natural lives and eventually die and are buried. Time passes and a thousand years later with no context available to them, Archaeologists dig up the bones and conclude the first one was a woman and the latter one was a man. That's the difference, the former has to try and convince people they're really a man because physically they're 100% a woman and the magic has effectively rewritten history as if their body was always female, while the latter has to convince people of the opposite because they are not women biologically and they are still missing the relevant organs as well as the fact that their body's growth as a man up to that point is still set in stone.
In all of human history so far, exactly 0 trans people have changed their sex. They've legally changed their gender, but that is not your biological sex. You say you were born in the wrong body and want to try and fix that? Great, work hard and do your best to live true to that, perhaps it will bring you comfort. Transitional surgery and drugs however are not a magic spell and should never be mistaken as such, and as for people who call themselves "trans" rather than as a "woman" or as a "man" and nothing else then I have to greatly question their motives, because if you believe you're really a woman mentally then why would you ever do anything or call yourself anything that would cast doubt on that 'fact'? Just be a woman and call yourself as such, end of story.
Have you ever heard the expression that "sufficiently advanced science is indistinguishable from magic"? The only reason you can make that argument today is because genetic therapy, hormone therapy and surgery haven't advanced enough for you not to tell the difference in every trans case (even though there are a lot of trans people out there today that pretty much "pass the social test" and get ignored as cis, especially fully transitioned trans men).
However, your argument doesn't work on this manga chapter, because the character has his mind intact, despite his body being a woman, which means the magic didn't go all the way, as you'd hope. Knowing the author, I'm pretty sure he'll covey the idea in the next chapter that the rape will cause him to have a woman-like mind (whatever that means to the author's degenerate brain), but that's the fucked up thing you'd come to expect. It's not magic though, it's mind break.
You also ignore the fact that there are women out there that are
genetically XY, but have a female phenotype, and they were simply born this way.
