Seems to me that if you're that squeamish about which parts of an animal you will eat, you should become either a vegetarian or an American. True, the MRM slurry is disgusting, but some of the examples you quote of parts which you seem to be saying are unacceptable are a bit narrow-minded:
Skin - Peking Duck, or crackling on a roast joint of pork, anyone?
Cartilage - probably with you there, although it's presence as a gelling agent in stock is useful.
Bone - not so good, but the marrow on the other hand...
tail - err - oxtail soup?
offal (heart, lights [lungs], sweetbread [pancreas], tripe, t e s t i c l e s, etc) - you are an American, aren't you?
udder - I've never eaten tripe, but many people swear it's a delicacy, so why not udder?
ear - again, never had the opportunity, but on one of the River Cottage programmes pig's ear was visibly an enjoyable nibble when sliced thinly and fried until crispy.
I've also eaten brains. Just the once - wouldn't bother again, as they were extremely bland and pointless, IMHO.

.and anything apart from brain and spinal cord which have been banned recently

Sausages have always contained items like that. It's often said of the pig that you can eat everything except the squeak. The whole point of sausages, and brawn, is to use up the cheaper cuts to improve the overall economic proposition of a pig. As I said at the start, the excesses of MRM (often a high pressure hose is used, not a "machine") are disgusting, but for thousands of years butchers with sharp knives made organic, free-range, traditional sausages containing all sorts of odds'n'ends.So, when the label says contains 60% meat minimum, you know what to expect. Lips and eyelids may well be there!
Remember this when you next eat a sausage.......
