This is my point, this is a timeless Trope for a reason, it KEEPS being included in stuff nowadays because clearly it still is considered that way...the difference is that in modern day where 'sensitivies' are so much bigger, louder, and more widespread than they were before (Thanks mainly to social media), the overall widespread/loud 'annoyance' towards them is a lot more noticeable, things that everyone had no issues with in the past now you can see countless people bitching about in Twitter and the like because they can't differentiate between reality and fiction. Is not like seeing these kinda behaviors in anime or games would actively encourage people to do it IRL, is like the old dumb argument that kids playing GTA would become criminals XP
Or maybe people may have reservations about playing as someone who spies on naked women. The world of DxD doesn't view Isseis action as anything other than morally disgusting either by the way, otherwise he wouldn't get attacked by the entire Kendo club and be outcasted from the rest of the school.
Spying on women as they change isn't a timeless trope in
anime, I've only seen it with DxD personally. Accidentally walking into a bathroom where there are naked women
is a trope however, but the end result is always the MC's nose bleeding and then promptly getting beat the fuck up (For no logical reason).
Sidenote:
I agree with most of your spiel, but it has nothing to do with tropes. You can differeintiate fiction from reality and yet still depise the actions a character takes. For example, if you watch Beserk is it "sensitive" for hating the rapists in the anime? And to bash the
characters? Or bashing tropes you find stupid? It's one thing to claim that video games and anime are the sole reason for why the world sucks, it's another to dislike certain tropes and/or characters that you find distasteful.
I don't watch Ecchi anime anymore because I don't like alot of the tropes that come with it:
Dense Protag, Eternal Virgin Protag with a Harem (*cough* Issei *cough*), Nosebleed when seeing naked women, getting beaten senseless when accidentally seeing someone naked, etc etc. It's all stupid bullshit, which is why I started watching more serious anime like 91 Days, Cyberpunk Edgerunners (Main character becomes an actual man and not a spineless bitch), Monster, Elfen Lied (Sad as fuck), etc etc because it annoyed me so much.
I
can get over the stupid quirks Issei has since he'll actually get action in this game, but if it weren't for that I'd never be interested in DxD outside of OC Fanfiction where an actually capable character is inserted.
Another Sidenote:
I actually don't mind the spying on women stuff, just the lack of skill and dipshit-ery. Issei complains about not having a girl friend and then goes and spies on half the female population. Like, no shit nobody likes you, you're a fucking weirdo. If he atleast double-downed on it and acknowledged the consequences I'd have more respect for him, but he doesn't.
AND, If he had half a brain he'd have gotten in the good graces of the Kendo club by exposing the other two's attempts at spying over and over until he gets in the good graces of them. He could even set up cameras and act like they did it to get him in the door even more.
