Why? Is the idea that meat has a unique ethical component that a consumer must grapple with up close by killing and butchering?
There seem to be many items we consume that have complicated and unethical production processes, but nobody goes around telling people they need to make their own cell phone or t shirt at least once in a while.
I've developed a similar stance to most products, and have largely abandoned spending money, exactly because factory farming is not that much different from making a cheap T-shirt, if not worse, in terms of cruelty and environmental damage.
for food those are actually more well known, and we are starting to care about that more, but the demand for eggs from cage free hens is really not much different than a demand for better working conditions for factory workers, or for environmental friendly production processes
Maybe we should.
But do it from first principles, I want to see ore mining going on :-D
