I never used to dislike them, oddly enough I started disliking them not long after Rafa left them. I'll never forget the night they went top after a nil nil draw at home and it was greeted by loud boos at Anfield. That and the whole Suarez thing and Rawk becoming Nazi Germany, a forum I used to quite enjoy. Having said that, I work a lot in Liverpool and they are generally sound people and often have nowt but good things to say about us, our club etc. And they f***ing adore Rafa they really do. Even Everton fans respect him.
Living in the Wirral I find exactly the same thing. A lot of them are just bellends online really.
