I gotta be honest, it is because I imagine myself in that situation and empathise immensely that I am compelled to comment here.
Your comparison (with regard to the pictures above) is extremely logical and I do not see how people associate adult connotations to images that are merely 'fun and innocent' How can an adult look at them and see anything sinister or imply perversion I just don't get it!
In answer to your question I would be devastated and probably a little traumatised. I would lose a portion of my faith in humanity too I imagine.
