Well, I can't Prove All the Disney stuff is intentional - but I would say it is as a result of my personal experience and what I plainly see in Disney's studio's work.
Personally, I do feel something sort of creepy surrounds Disney. I guess I've felt suspicious of him in much the same way I might a cub scout leader who shows a bit to much interest in the cub scouts. It's a difficult thing to define just what it is that moves one from well intentioned roll model to a level of suspicious over involvement - but there is a line. The creepy uncle factor. I always felt Disney was across the line and into creepy uncle territory. As a child, I liked the cartoons but didn't like him very much. I couldn't have said why then and I can't now, but there it is. Consequently, it is easy for me to believe that he would attempt subliminal seduction and to sexualize children. When I see images of naked ladies in the background window of the Rescuers, I am not surprised. Phallic symbols in the art work don't surprise - and I do think it intentional - it doesn't even match the rest of the castle architecture. Donald duck leering at children's crotches as they ride his doesn't surprise me. It all seems to fit the creepy uncle I've always felt he was.
But tiz all just my opinion.
