You're clearly drinking the wrong beer.
I'm not going to advocate that everyone like all beers, it can definitely be an acquired taste, but I will say that there are so many hundreds of varieties that to lump them all together as "taste like piss" is wholly unfair. And if you've never had anything other than a macro brew (Coors, Budweiser, Miller) then you've only tasted the garbage anyway. It's like declaring all seafood is rehashed fecal matter becuase you ate at a Long John Silver's once.
