I do like this to a point, but if you've shared your loyalties between two clubs because you were born in London but were brought up in Sussex and have consequently moved back to London, but still have a season ticket in Sussex... are you a 'plastic' fan? And if so to whom are you plastic? Or...
Good for you bushy and I'm well chuffed for the 'LondonBlues'... I, like you, have experienced the Chelsea downers, nearly going out of business, 18th in the old Div Two... football people understand this, 'patriots' don't seem to have a place in their heart for anything but themselves.
I wore my shirt one day last September on holiday in Egypt. I got some bloke shouting 'Seagulls' at me, turned out he came from Shoreham. I wasn't embarrassed to wear it.
