If you mean what I think you mean, then you’re being down voted because your phrasing isn’t clear. I interpreted your comment to mean that removal any of dark skinned characters would often make the depiction less historically accurate, due to their historical presence as a minority of some sort across much of medieval Europe. If so, I agree that is amusingly ironic.
I made a few adjustments: “This piece, consisting of a standpipe connection and highrise pack, really makes me think about the critical infrastructure needed to maintain a stable and safe building. I think the artist intended it as a statement on the intersection of infrastructure and safety regulations in our society.”
