who on earth thought corn-soybean mush was a good idea.

I have a lot of problems with some of the mentality of too many members of the food activist circles, they see food politics as a meat verses vegetation issue, not a class or corporate one. I would also add my complaints-to put it mildly-about the orthodoxy over calories and fat, but that's a rant for another time.
