Out here in Thailand, all the innards are eaten by someone. If you order a meat dish it may have lots of mixed meat added. Slowly though all the old-style dishes are fading and people eat more like they do in the Western world. After living out here for a while, I've become used to eating more of the internal organs. I guess the things I don't like are lung and tripe. I think they also add rennet sometimes to a certain meat dish. That was disgusting. Blood added to soup or meat dishes is tasty.
