I'll have to modify your title a bit. I don't hate anything I love, and I don't hate the fact that I love them. You could call this list "Things that, if I were a shyer or more sensitive or insecure person, I might be embarrassed to admit that I love" or "Things that I love but my wife hates."

FOOD, DRINK, ETC.
Sardines, right out of the can, with crackers
Pork rinds (even though, whenever I eat them, I usually manage to inhale a crumb or two and go into a coughing fit)
Strange and exotic liquors, such as slivovitz, aquavit, tequila, Myers Rum--whatever I can get my hands on (but generally not liqueurs)
Cigars (but I don't like the really cheap ones, and I can't afford the really good ones, so I usually compromise)
Cigarettes, but only when I'm out drinking with other people who smoke them, which is seldom
Braunschweiger sandwiches
Canned corned-beef hash
Dill pickles
Sauerkraut
Pickled herring
Pickled onions
Pickled peppers (do you see a pattern here?)
Calamata olives (I even drink the juice they come in)

ENTERTAINMENT
Benny Hill. The Marx Brothers. Laurel and Hardy. The Three Stooges. Our Gang/The Little Rascals. Amos 'n' Andy (at least I think I'd still like them--It's been a long time since I've seen them).
Yeah, porn too, to a point. Like, I'll tune in the Howard Stern show once in a while after my wife has gone to bed.

MUSIC
Anything really exotic: Tuvan throat singing. Tibetan Buddhist monks' chants. Balinese gamelan music and "monkey chants" (from dramatizations of the Ramayana). Pakistani Sufi music. (Well, I probably wouldn't want a steady diet of this stuff, but I own at least one recording in each of these categories.)
Things not so exotic, but certainly not what I grew up with: Cajun/zydeco music. Acoustic "country" blues. Tex-Mex music (or would that be Tejano or Norteno? I never know what to call it.) Jug-band music. Polkas.
