I believe there are a lot of misunderstood food ingredients, sardines being a perfect example in this case. They are usually brought up to indicate "things packed like..." or making a reference to low-brow foods. I don't stand for this, since sardines are pretty amazing when prepared right (and so are all the foods you dislike). I used to hate capers, olives, and celery to name a few, but once you have these ingredients prepared in the RIGHT way, you will forget your distaste. Sardines also happen to be a powerhouse healthfood, packed (like sardines) with protein and omega fatty acids. Just try this: char some bread, mash in avocado, sardine and squeeze some fresh lemon juice on top. Don't forget to season generously with Maldon sea salt and freshly ground pepper. I promise, if this doesn't change your mind then maybe I'm wrong: you just really don't like sardines.
