No. But once upon a time I was. I was even a member of the working group that re-designed the County Council's logo in the early 1990s (the one that is misrepresented on the Sussex Flags website, btw), so I am very familiar with the history of how East Sussex, West Sussex and Sussex have been represented over the years.
Oh well I did ask.
I still don't get your point in post #11 about East Sussex Albion fans getting taken in by the Sussex flag.
I have had a blue Sussex flag for a while now and also a sticker of the flag on my van, and have you noticed the number of Blue Sussex flags in the South West corner at the AMEX? How do you know where they live?
I think it's a good thing to have a Sussex flag, we do sing ' Good old SUSSEX by the sea" not good old East/West Sussex by the sea.
I've seen these flags also at Sussex County Cricket Club matches, the cricket club is called SUSSEX CCC, not East or West Sussex CCC.
I went to Devon for a holiday about five years back and lots of tourist information centres were selling Devon flags, car stickers etc, they seem very proud of their flag and county down that way.
When I came home I was in Lewes the following week, I called into the tourist information centre to see if they sold a Sussex car sticker, flag or even a pin badge, I came away empty handed.
I grew up in Brighton and when I was a kid if anyone asked where I was from i always replied Brighton Sussex, not East Susex.
