I flatter myself to think that I would try pretty much any food once, if offered it. There a few things I can't stomach the thought of, but most things, I'll take a flier on. I'm one of those annoying people who will go into foreign restaurants and order without understanding a word of the menu. I'm rarely disappointed.
All that said, I think, if I could do it ethically, I would try human flesh. I don't find anything inherently morally wrong about consuming human. It's the way you obtain the meat that's the moral problem. But if it were legal and someone put in their will that, should they be killed in a manner which would allow it, I could try a taste of their body after they were dead, yeah, I'd try it.
I'm not sure how I feel about eating people who never agreed to it before they died, as in the case of being stranded in the Andes with a plane full of corpses after a crash and being forced to cannibalism to survive. I'd probably do it, but I'm not sure I'd feel completely moral about it. If I didn't cause their death in order to eat them but they didn't consent to being eaten, it's a bit of a gray area maybe.
Of course, if I eat meat of any kind, it was pretty much without consent, as animals aren't capable of informed consent by most metrics, and was almost certainly from an animal which was killed simply so I could eat it. And that's leaving aside the ethical problems of environmental devastation and animal cruelty. Even the most careful and ethical consumer of meat is still killing an animal without its consent in order to eat it. Various indigenous cultures throughout the world have dealt with this fact in various ways, but we inhabitants of "modernity" shove that under the rug and distance ourselves from the act of killing as much as possible.
For the purposes of full disclosure, I'm not a vegan. I should be. We all should be. But I'm not. I violate my own moral compass and eat food derived from the mistreatment of animals. I'm not proud of this.
Humans are just animals. Sure, in the complex moral calculus of life, I will acknowledge that I value human life more than that of other animals, whether that's blinkered of me or not. I am something of a human chauvinist, I guess. I'm not particularly proud of this either.
But it still doesn't explain why I have moral qualms about eating human meat, even if it comes from a human who was killed for reasons other than being eaten and in whose death I am blameless. I don't know. It's hypocrisy, I guess.
All this to say, I'd try long pork under a certain set of circumstances and I don't think I'd be bothered by the act itself, even if I were bothered by the method of procurement. They claim human tastes like chicken. I'd be curious to find out, if nothing else.
