And you know what? That's OK. I'm not one to say you should like beer, so if you don't like it, you don't like it!
But...I am one to suggest that if all you have ever had is Miller (lite or regular), Bud, PBR, and maybe a Heineken or Stella Artois, then you owe it to yourself to try some other types like Belgian Dubbels/Tripels, Quads, or Stouts/Porters (Guinness is a good entry point there), and something like an American-style IPA (Dogfish Head 60 min might be a good starter). Or any of the other styles like Saisons, Flemish Sours, Amber or Brown Ales, Scotch Ales, wheat beers like Hoegaarden (or even the US mass market equivalents like Blue Moon or Shock Top), and on and on. There are so many taste profiles out there that if you can like beer, you find your way. I have successfully introduced craft beers to so many people who thought all beer tasted like Bud or Corona, and they really liked that Fat Tire or Hoegaarden or Sierra Nevada Pale Ale. And then discovered all the other great tastes, or sometimes stayed with what they liked - one of my co-workers really likes wheat beers, and not much else, and good for him!
But if you honestly don't like any kind of malty-hoppy beery taste, then none of those are going to appeal to you, and as I said, that's OK!
