They have to do some bending to get people to notice its existence in the first place, let alone deem it worthy of trying a first time. The fact that people insist on calling it by its French name, rather than "fat liver", is a testament to the marketing that has to be done to support interest in it.
I don't pretend this is a cure-all, or that we can always end livestock torture by not promoting its tasty products -- that would be endorsing a "just world fallacy". But sometimes we really do make our hard choices a lot harder than they need to be.

The study of variable quantities is called "al-jabr" not because mathematicians want to make it sound exotic, but because of historical accident. Unless you have particularly good reason to think otherwise, I would guess foie gras is the same way.
Foie gras, the delicacy made from the liver of a very fat goose (or sometimes duck), is believed to be unethical and is therefore frequently banned. For a long time, it was believed that the only way to properly fatten a goose is to continually force-feed it through a tube over several weeks, which is probably a highly unpleasant experience, although it's difficult to tell. Recently, Spanish farmer Eduardo Sousa revealed that under highly specific conditions, you can get geese to fatten themselves voluntarily.
Geese will instinctively gorge themselves when winter is coming on. Eat a goose right after it's fattened itself up for the winter, and you get a delicious treat that died happy. The problem is that geese will only do this if they believe food may become scarce during the winter (or their instinct to gorge only kicks in when the environment is such that that would be a reasonable inference; it's not clear whether it's the goose or evolution doing the analysis). If they realize that food will remain available during the winter, they eat normally. And there are quite a few possible clues--farmers trying to replicate Sousa's setup have discovered that cheating on any part leads to unfatted livers.
