what strikes me as odd, is that if you were even going to eat a foetus in a stew, you would chop it up first, wouldn't you? i've not got much education is cooking dead creatures, or in preparing them for cooking, but i don't recall seeing many, if any complexly formed creatures (as aposed to small fishes and snails and prawns and clams, etc) being so completely intact like that inside a prepared meal.
even with chicken, or pig, i thought it was deemed more efficient, hygenic or just plain easier to cook evenly and eat, if you at least removed some of the ickier inside bits, or even just superflous outside stuff like hair, before cooking it? it'd be really tricky to eat a whole foetus like that- especially in a soup- you'd have to fish it out and break bits off, on a plate, with a knife and fork. you couldn't really do it in a bowl, with chopsticks, could you?
also, i saw the article was on an anti abortion site, which cites the article source as being UK LifeLeague. the lifeleague website is erm... interesting. as well as being anti-abortion, lifeleague also seem to be very much traditional strict christian 'family roles and moral values' based, as well as anti divorce, anti feminist, anti homosexual/pervert (they clump homosexuals right in there with perverts and paedophiles.... how inclusive of them!) and anti sex-education for teens.
i'm sure that both groups have a very clear agenda in posting these images, and so its not exactly unbiased material. i think its staged, and has been created/used as a shock tactic.
