Don't really get that. You are implying that people from the east of the county are simple and support the Albion. Weird inferiority complex some W Sussex people appear to have. Sussex is Sussex be it east or west.
Years ago there was a poll that showed our support was more in East Sussex. Unsurprising as Brighton and it's smaller neighbor Hove are both in the east. I suspect some in Brighton have included themselves in 'other' in your poll.
