Just opened this thread for the first time since I posted in it (I sometimes lose track of these things!)

I totally agree with you 100%. But the thread was about Broadway, so that's why I mentioned it specifically. Not sure the if your "welcome to the thread world" comment was necessary, but whatever.
I've seen very few examples of size-blind casting. The only one that comes to mind off the top of my head is Alysha Umphress in On The Town, which was great to see. I'm sure I've seen others, but that's one of the only ones I can think of where it directly fought against the notion that only skinny people can play sexy, desirable characters, and where it wasn't written into the script as a theme of the show.
I admit I totally forgot about Hairspray in my original post - it probably would have been a better example than the ones that I gave.
