Sure, I can well believe that SOME Albion fans hate Pompey more than Palace, and that could be a proximity thing if you're in the west of the county.
But we're talking "traditional rivals". They have never been our traditional rivals. Any football fan who truly knows his spuds would say its Pompey/Southampton and Brighton/Palace. At no point did we "switch" from a Pompey rivalry as such, its just never been there.
Ive lived BN1, BN2 & 3 all my life I'm 48 and promise you I hate PFC more than I hate Palace......
