No. That's just a fully clothed character. Any workplace where that would be considered "NSFW" is the kind of place where getting caught browsing Lemmy at all is NSFW.

No. Worrying about this is like making dogs and cats wear pants.

I would personally adhere to US Beachwear rules unless mods specify otherwise.

1. No nipples, exceptions being for explicitly male, of photographs of cultures that generally do not cover breasts, or certain artistic or medical references.

2. No pubic region that reveals any genitalia or anus.

3. There is no third rule, literally anything goes, including the image you were wondering about.

So while some people might object to a lot of the content we see, I don't personally think it is problematic. Especially when your instance has images collapsed by default, except for thumbnails.

Bilateral half naked or radial half naked

This is a weird thread... Lots of people really give a shit about what others think about the content they consume. There's also a lot of strange presumptions about people who watch anime and how it's creepy when adults watch it. If you were just described above, maybe you should reevaluate some things.

If you would get in trouble for this image on your phone at work, then you really should not be on Lemmy at work. I'm sure there are perfectly acceptable threads for your workspace on Lemmy, but then again, people used to read the articles in playboy magazine. Also, the example image is only sexual if you sexualize it, which you are doing by saying it should be marked nsfw. If the local news stations are comfortable showing gymnasts and swimmers and volleyball players in their respective uniforms, then why should this be any different? Lastly, if that drawing is making you uncomfortable, I don't know how to help you because this is so so so incredibly far from the worst content you can find on this site. Maybe you shouldn't be on here at all if that's the case.

It's only weird if you make it weird and this whole thread is making it weird.
