I like tomatoes but do not like ketchup.
Similar; I eat tomato sauce all the time, with a variety of foods, but I can't stomach actual non-squashed tomatoes.
I suppose there's also the fact that throughout school, etc, as well as at home, I was always ridiculously well-behaved and rule-abiding, yet I've never actually had any real investment in or attachment to rules. I'm pretty much an anarchist by nature, but looking in at my behaviour you might think I followed rules religiously. It's sort of the same with my speech and manners when meeting people in person - I tend to be rather formal and structured, but my need for hierarchies or clearly defined manners is almost non-existant.
Let's see...my sense of humour can be very dark and "twisted", yet my actual tolerance for fear or distress to others is incredibly low. I'll laugh at, and find genuine humour in, things to which most people say "you can't laugh at that!", yet despite this I'll get very uncomfortable long before most people if the content of the "humour" crosses over into reality.
I love animals - always have - yet often display a wariness or even fear of them where most people would be entirely comfortable.
I feel both restless and angry almost all the time, yet somehow also at peace in a way I don't think many people are.
I suppose the big one: I'm deeply devoted to civilization and human society, but I also consider myself to have ideologically "parted ways" with them, and want them completely restructured in a way that, as a good friend of mine notes, goes "far beyond any radical politics". I'm both forever homeless and yet comfortably roosted. I don't consider myself to "belong" but simultaneously could never feel I didn't.
