Shops that have dumbly banned foie gras - rather than trying to offer ethically produced foie gras - still sell goose and duck fat from foie gras birds. Places like Harvey Nics. Oh the hypocrisy! And 'posh-rustic' foods like cassoulet, duck confit and pâtés are included in this by the way - they all contain birds that have been force-fed. Because one great thing about foie gras is that none of the animal is wasted.
Now, these birds were free-range and happily hanging out in seriously spacious fields most of their lives. They have much nicer lives than most pigs and chickens. So, foie gras and other products made from foie gras birds are more ethically sound than the vast majority of chicken or pork. But if you're against force-feeding, don't bloody buy French goose or duck fat for your roast spuds! And if you're against foie gras in principle, you cannot justify buying intensively farmed chicken or pork. It is worse than foie gras.
