Nicely put, Pineapple. Actually, I think we have something of a cultural disconnect from our past, here. I mean, I'm barely a quarter of a century old, so what do I know...but I don't think the idea of rape would really cross anyone's mind back when the ride was first designed. I figure one would more readily assume that these all-too-forward suitors are just doing a poor job at wooing their reluctant maidens, much like the aforementioned Looney Tunes skunk.
As for objectification in the portrait...well, let's just say that the model for the portrait looks more than willing to get herself painted. She looks like she's thinking "Man...I look AMAZING!" And hey, what's wrong with that?
