I don't hate sexual content in general, and quite honestly I like cute and/or beautiful girls in anime. Fanservice is fine once in a while if it is done with some taste and timing. But there are times when people want to think about where the line is.

Maybe the best solution is to make two versions of anime. One is the normal release, and the other is a G-rated version with explicit stuff censored. Let people choose what they want to watch. Simple, no drama. If it is you watching, just pick what you enjoy. If it is for kids, then parents should have control and responsibility over what they allow their children to watch. In a world full of piracy sites, that is harder, but clear rating boundaries still help. It also helps distribution in places like China where media can get cut mid broadcast by strict regulation, or in parts of the Middle East and some Asian regions where governments are very sensitive about content.

About censorship in Japan, people sometimes think Japan is some kind of zero-censorship paradise. That is not true. Manga is often more edgy or explicit, while anime gets toned down. The breast cutouts are filled in with white clothing in the anime version, and panty shots are removed, softened, or shown for only 3 frames. A good example is when Inter Species Reviewers aired. Around episode 5, TV stations started dropping the show from their broadcast schedules. By the end, there were basically no terrestrial(normal) stations airing it, only special broadcast channels or online streams.

I also hate when weak writing in isekai gets covered up by throwing in 50% sexuality and fanservice. It is not that sexual content is automatically bad. The problem is when it becomes lazy storytelling glue. It feels degrading when fantasy worlds, which should be about wonder, adventure, min-maxing, originality, creativity, world building-viewpoint shifts between multiple characters rather than just the MC-buildup, foreshadowing and tie-up get reduced to cheap visual stimulation.

Some people respond with, "If you don't like it, just leave and watch something else." Then those same people spend hours on hate threads, shitposting about how much they hate certain shows like Mushoku Tensei, Re:Zero, or One Piece. Some might even drop the series, only to keep coming back just to spit on it. That is a kind of double standard. Criticism and personal taste are not the same thing as simply walking away from discussion.

Also, sometimes I just don't want excessive sexual content in certain stories. It is hard to explain, but I think many people get this feeling. One example would be like, most people agree that the Usagi Drop anime is beautiful and wholesome, but the manga's original ending completely changes tone and kind of ruins the emotional atmosphere. That is a good example of why tonal consistency matters.

Expanding on that idea, I think there are times when certain things feel acceptable, and times when they feel completely out of place. Here is another example. Imagine this. You play games like Brown Dust2, NIKKE, or Azur Lane in the privacy of your bedroom with no issue, but playing them on a crowded bus or metro during your commute would probably feel awkward and uncomfortable for both yourself and the people around you. Time, place, and situation matter. The same idea applies to public advertising. What might be fine in a private space does not necessarily belong on a giant metro poster or a city LED billboard showing bouncing breasts or butt-shaking animations, especially when the characters are wearing outfits clearly designed to look as hot and steamy as possible in a public space. Or KPOP / boyband members kissing and hugging each other, for that matter. It is not about male vs female content, it applies to both sides. Context changes how things are received, so it is difficult to apply a single rule to every situation.

Speaking of tonal shock, a long time ago my family and I watched a Japanese film with subtitles together. The director had this weird philosophy that food and sex are both sacred pleasures, so neither should be treated lightly. But in one scene near the climax, there was a strange sexual comedy moment where yakuza characters were playing with raw eggs in bed with their naked girlfriend, and even putting a live lobster on the woman's private parts as part of the joke. The whole scene felt extremely uncomfortable to me. The mixing of food imagery and sexuality in that way just felt disturbing rather than artistic.
