Yeah, it can be annoying, especially when they are posted randomly just to seem to get a rise out of people or to troll as I've seen of late, like those who say "Smash is a party game" on the gaming side and elsewhere on the web. Their is arguments to be had and good points on both sides and good discourse can happen, but a lot of the time I've seen people not want to engage or haven't got much say expect spouting memes, which is honestly something that gets really tiring in online discourse.
The one of these hot takes that was just eye-rolling and I'm surprised last so long was there "Aquaman sucks" jokes, all based on the Super Friends version and I'm convinced most people who kept going on and on and on and on about never watch Super Friends or read a Aquaman comic because it was the same jokes every time (because repeating someone else's joke me you funny right! /s). It went on for so long that the jokes kind of got warpped and didn't make any sense like "He can't live outside the ocean!" (what?) or "Anyone can get his ass/I ca kick his ass!" which... HAHAHA okay, even somehow he doesn't have powers on land, he's built like a body builder so SUUUUUUUUUUUURE random on a forum board, I totally believe you can kick his arse /s
What was funny was seeing all these people plus hack comedians desperately try to find a replacement for the Aquaman jokes prior to the DCEU one coming out. I remember some trying with Hawkeye... Seemingly not knowing the comics have already been doing that for decades and the Age of Ultron kind of killed that attempt, Fire Storm, Ray Palmer, Namor etc. All the same joke with the name changed, all failing because apparently writing original and clever jokes is hard.
You are not wrong, but I think her point is that it is common to take ideas that inherently belonging to a specific domain, try to scale and age it up and introduce all sorts of issues.
In this case, Batman is super consistent and pretty harmless as a kid's property but becomes increasingly problematic on multiple fronts when you try to age his stories with the audience.
The question then becomes this: is the character the problem, or is the fact you dropped him in a context he may not have been designed for the problem.
The thing is about Batman though is that I don't think that true. Like reading the original Golden comics, especially comparing them to Superman or the All-Star comics, they often ended up coming as aiming for an older audience (not necessarily adult), hell people talk about how the Joker has gotten too dark nowadays, the original Golden Joker was a straight up relentless killer.
The thing people forget is that the Silver Age for Batman, the time of the multi coloured batsuits, Bat baby etc, nearly killed Batman as a comic, sales dropped massively and DC nearly cancelled Batman books, only not because of the success of the Adam West show which actually WAS more mature then the comics at time (even if fans in the 80s and 90s unfairly stigmatized it) which even then, was just a small boost. It wasn't until the works of Neil Adams, Frank Miller, Gerry Conway, Len Wein and many others that Batman comics became popular again and it's this Batman that so much of his modern pop-culture is based around, where the Burton movies, the Batman The Animated Series, the Nolan and Snyder films etc.
That's the thing, the turning something for kids to be more adult already happened decades ago with Batman, I'd argue the issue is that people like with the Snyder films take that even further and then miss the point. The X-Men comics which also had this happen between the Lee books and the Chris Claremont run also suffer from this issue.
