Well, maybe I’d agree with you IF your picture even exposed anything, and now I see “exposed” takes on a new meaning for some. Adult nudity in front of children is not what is happening, now is it? At least be honest.
Sheesh, I accidentally “exposed” myself as a young child on the playground when I wore a dress, as did so many other children. We did wear shorts under our dresses (dresses were required attire at the time) in gym class. I’ve seen boys take leaks as a child and no one considered any of it perverted because it wasn’t!
I’ll go back to the days at the pool and men/boys in speedos, yes, they had bulges, and that’s how men are made, lesson over. Were they deliberately exposing their goods, maybe, maybe not, were mothers and fathers jeering at the sidelines at them? Were they asked to leave? Not that I remember.
I think a person could reasonably explain to their child, if they chose to take them to the library for story time that the people there were men dressed up as women, or that they were Christians that wrote a book. Of course they could also just leave the library or stay home and not take them if what the found was offensive.
