Yeah they do. Quite a few people who grew up in Mid-Sussex supported Palace, so we were always more bothered about Palace than Pompey. Understandably Brighton fans who grew up towards Portsmouth would have seen them as rivals.Anyway, our true rivals were always Pompy. And we rarely played them. And it really meant something only for those who lived in places like Bognor (in between). Nobody south of Gatwick supports Palace surely?
