None of what you are saying is necessarily untrue but you still have the cart before the horse. Soy is as widespread as it is because we can use it to sustain industrial livestock farming, it isn't some happy side effect as much as it is the deliberate intention.
it's not accurate to say the soy beans are grown for animals at all though. they're grown for markets and soild health. markets value the oil far higher on a per pound basis than the rest of the bean. I just can't believe a telling of the story of soybeans that places animal feed so prominently, when it's literally the industrial waste that is fed to animals.
I have read plenty, (you didn't think I was looking all this up just today, did you?) and i have told you a story in which the objective facts are indisputable. the only point of disagreement we have is how to interpret those facts, and I have given actual reasoning for my interpretation, while you said "look it up".
