Note
Exploitation = purposes only
Never define exploitation as for your benefit, against their will, for gain or pleasure, or against their interests. Benefit invites tradeoff arguments or denials, addiction, habit, knowing meat causes cancer, eating despite guilt. Will invites consent debates, no will, would consent, can't consent, or broken animals seeming to choose it (horses 'wanting' to be ridden). Gain/pleasure lets them dodge; interests lets them justify whenever they deem it 'in the animal's best interest.' Always: the act of using someone for your purposes or as a means to an end.
