If that's what they wish then let them, you don't have to be so judgmental about it. If you want to make mods that appeal more to your ideology then make them yourself, form a team with other modders. Look at Nehrim as an example. They made basically their own world from combining the talent of many modders. So someone wants to make an anime/manga/comic book/fetish mod, so what? It's not a waste if they are doing what they enjoy. I for one wish their was more variety in reasonable armor mods for my characters but I'm not going to complain to much about it because if I really wanted it bad enough then I should just make it myself.
I think most people just complain because they think it makes themselves more elite among their peers or to satisfy their ideological "cliche". Half these people are only taking things at face value, if I put up mods based on "Vinland Saga" or "Berserk" not one of them would complain, that is until I say it's from Anime/Manga, then the flood gates open. It's as if as soon as someone mentions something is related to Japan, the "weaboo" alarm goes off.
By that logic, why did you read my post and complain about it if you didn't like it? You shouldn't be so judgmental about other people's posts. You're probably just posting to make yourself seem like an anime-guard elite.

You're also barking up the wrong tree, here, as I generally like anime, and don't particularly complain about anything being added just for being anime-related. I only complain when it clearly clashes with the already-existing art-style (unless it were some sort of total conversion that replaced the whole art style).
Also for that matter, I used and enjoyed the Japanese-made overly elaborate hair styles.
The complaint I was making was not about there being anime-related things, but rather, the fact that nudity and six-related content are the bulk of the really advanced mods. Yes, I've seen porm before, but I don't particularly enjoy the idea of literally stripping bandits naked when I just want to sell their armor for a bit of extra cash, and those "nonconsensual sixual content" mods that involve bondage monsters or "potions" of bodily fluids are just right out.
To say that it's a little annoying to have to sift through 100 lingerie or bikini-style outfits to get to one reasonably-cut new type of armor mod is hardly going on an ideological rant, for that matter.
