that it is morally defensible in any way to create an intelligent creature and then force it into a state of utter lifelong dependency just so that you can exploit its biological processes

Interestingly, I don't have issue with people who hunt for meat (provided they follow generally accepted responsible hunting practices), but I have a big fucking issue with animal agriculture.

The quoted section is the distinguishing factor. Creating sentient life for the explicit purpose of exploiting it really rubs me the wrong way.
