For me, it's the lack of knowledge of and deception used by food producers that irks. Because it stops people making an informed choice. Did you know for example, that free range hen producers for big companies get around the free renge thing by training their chicks to not want to go outside? So they are kept in closed barns until they are of egg laying age, at which point the barns doors are opened, so that they can say the Hens have the freedom to roam, but by then the hens choose not to. And free range is perhaps the one change more than anything that has been brought about by consumer choice. But big multinational food producers don't care about any of that. So they find ways to cheat. Just like cows that are grass fed don't get ecoli in their guts and don't then need antibiotics. In fact they don't need antibiotics at all. A corn fed cow needs only to be grass fed for a week or so to get rid of the ecoli. I really don't mind if people eat meat, animal products, or not. I do mind though how that food is produced, and I would hope that meat eaters too would care about the quality of the meat they eat. Price is an issue of course though.
