I am not a vegan, or even a vegetarian, but I recognize my own cognitive dissonance on the issue. That’s not to award myself any brownie points or anything, just a statement of fact. Indeed, it likely only makes my own cognitive dissonance on the issue even worse.
I think even the most avid hunter or advocate of the carnivore diet would decline to offer any defense of the factory farming industry, which is an important subcategory of the overarching animal rights issue in general. But there is more hypocrisy involved than just the overt acceptance of factory farming imposed by law and the tacit acceptance of factory farming in everyday people as they turn a blind eye to it and continue consuming animal products, thereby maintaining the very demand that resulted in the invention of factory farming.
