I know that it's good and healthy, make no "bones" about it! But part of my squeamishness is over pieces and parts. For some reason I have no issues with using backs, bones, and organs from birds when making a nice poultry stock, but from land animals it's different. It's part of the reason I don't eat bologna or hot dogs. I don't enjoy their flavor overall anyway. And I know "what you don't know won't hurt you" but if I am making the souse myself, I know exactly what went into it, and my souse would not be souse because I wouldn't be using all those pieces and parts!
If I had to kill and butcher my own animals I would totally be an ovo-lacto pescatarian. I can catch, kill, and clean a fish no problem but birds and mammals are a different thing.
