Why exactly is this problematic, but the deaths of Uncle Ben and Bruce Wayne's parents aren't?

At this point, fridging is such a vague and nebulous term that it is completely meaningless

Kyle was doomed as a character from this moment, every power up and relevance he got from later writers always felt like overcompensation for his girlfriend getting fridged.

Cutting someone up and putting them in a fridge is an absurd way of killing someone.

Honestly, Kyle was doomed the second he lost Parallax as his antagonist. He floundered for years, never having the same relevance he had during that period of 1994-1996. The next few years would be him being relegated to the JLA which is the worst thing to happen to a Green Lantern because it means having to be downscaled as to not overshadow the Trinity. And then they gave Jade as his GF and it would continue to get worse from there.

We were originally supposed to see the fridge door all the way open and showing off her whole body, but that was too much for the editors so they changed it to what we got (and made some think she was dismembered because of such discretion).

Parallax won. He succeeded in rewriting entire story of green lantern to keep it forever as Hal jordan glazing

The Melancholy of Hal Jordan

Hasn't even Gail Simone herself brought this up?
This isn't the issue either. The issue was that half of those fodderized girls were basically just meant to die to begin with and were never very compelling relationships so you feel absolutely nothing when they die.
I wanna argue against this but she did get gossip-y about it.

The guys who refrigerator these girls do it because they go through breakups and divorces during their runs and feel like they can't write romances during those times.

I mean, I can totally see writing the love interest out of the story for a bit if you're having those issues. Say she went to be with her family in Canada or something. But I can't imagine any writer who was dead set on a certain couple would just kill one off, sounds like something you see amateur teen writers do.
I always just assumed it was shock value when they do this shit

Simone is one of the worst office bitches out there.

Which is a fair enough complaint on it's own merit without needing to invent a whole layer of imagined ISMs so you can get defensive about a secondary character.

Simone is one of the worst office bitches out there.

She seems like that one Gen X mom. The one who tells her kids not to be bullies or tells people not to be judgmental but the moment you're alone in the car with her, she has something to say about every fucking neighbor, co-worker, and acquaintance but it's okay because she only goes behind people's backs to talk mad shit about them.

Is Peter or Bruce having an incest relationship with their parental figures?

It literally was though. She died in a fucking Spider-Man book and we saw more grieving from Peter than her actual supporting cast.

She has an defined character arc with her own agency, shart for brains. Dying in a crossover like many characters do while established friends react naturally is not female genocide.

Because it was the perfect vector for feminazis to infect the comic space.

Case in point

Gail Simone was pretty ride or die for John Byrne up until it made her look too bad personally.

Dying in a crossover like many characters do while established friends react naturally

Hew own supporting cast was ignored so Peter could be the star mourner

Standard Gen X trait anon. They were the most cynically raised generation during a time when cultural values where coming into complete clash so the idea that people are tools to be used and disposed of is kinda par for the course with them

It wasnt.

Why exactly is this problematic,

Old stuff never had problematic scenes.
Here we see mutual love at first sight.

I can't believe that Yoshikage Kira is a pedo

I'm not going to pretend to know anything about Kyle Raynor or this girl whose name I don't even know but I'd assume it would be because Ben and The Wayne's were dead the same issue they were introduced.
I assume she was around for at least a little bit before this.

So a popular man mourning a woman is oppressing women?

the issue is a tendency for female characters to get fodderize female characters in lurid ways just to affect male characters,

Name 20 examples

Are you being purposely obtuse? The point is her own cast IE those important and more intertwined with her were shoved aside so a more popular character could be the focus on the mourning, it's like alright lets say your mom died and instead of your mourning being the focus everyone is talking about how sad the mayor is that your mom died

wtf a nuanced take on Anon Babble

The only reason it wasn't was because it was such a stupid, infuriating thing that a pissed off industry person leaked that it was happening and was being used to set up her coming back as a mutant for SYNERGY before it even happened, so that any actual "fridging" evaporated. Leaving only the basic, stupid PR stunt nature of it.

Had it actually been what it appeared to, sacrificing a now has-been teen hero on the altar of one of the stupidest Spider-Man events out of nowhere, then it would've been held up as a Super Fridging moment. A female character who began as the heroine of her own ongoing, dying in a completely different comic for a character she barely had any relationship with, to provide emotional torque for his own stupid fucking story? People would've had a fucking field day with that shit.

It just is, ok?

No, Major Force and pretty much everyone of the Captain Atom family are douches.

one example is enough to show that killing or crippling female characters to prop up male characters is extremely sexist.

But Alex WAS a prop. I understand the complaint of female character being sacrificed to give male characters development but Alex wasn't such a case because she was never a real character, she was not meant to stick around; she was just part of Kyle's origin story much like Uncle Ben is part of Spider-Man's.
An actual instance of a woman being "fridged", as it were, is when Black Canary was tortured and lost her powers to serve as motivation for Green Arrow, because she actually is a real character with her own history.

Because there isn’t a problem with lack of male representation in comics and pigeonholing them to one-note superficial background roles. Male characters get to have plenty of depth, variety and are everywhere so there isn’t any kind of an issue with killing them off. Where as with female characters killing them off for shock value after introducing them is a long standing trope that limits and diminishes female characters and every time you kill a long term female character like that you’re left with a deficit because writers aren’t creating and developing more woman characters to replace the dead one. So you just further marginalise a minority.

Imagine for a second if the genders were reversed. Barely any male characters around, the ones who are there don’t do anything except show up as boyfriends/husbands and don’t actually matter to the plot at all. And writers regularly just make new ones to kill them off so that the woman can be sad about it. Would you as a man think that’s fine and there isn’t a lack of male representation?

but Alex wasn't such a case because she was never a real character

I dunno desu, she showed enough character in five issues which made it that much worse when they got rid of her because she was Kyle’s best supporting character.
