Eating meat is a standard human experience, and while some have chosen not to eat meat, the fact others do shouldn't require censorship.
A reasonable human being can expect to see prepared food at restaurants, on people walking around while eating, on advertisements, at the grocery store, at street food vendors... And in this photo on the side of the road
Pictures of prepared food are also work safe, because a reasonable person would encounter such sights at work lunches, catering, in the kitchen, etc.
Therefore I don't think it's reasonable to ask Lemmy to censor pictures of prepared foods.
