flying it at the centre of power of a country whose minority constituents already feel marginalised (and didn't vote for the occupant) is highly insensitive
Oh stop dripping FFS, seems like a large portion of those constituents would happily be marginalised on a permanent basis and will doubtless, to a man, prove their self marginalisation by supporting England's opponents in every game.
And as for all that nonsense about the oppressed and the oppressors, I doubt for one second that anyone really thinks that Westminster has any more regard for its English subjects than it does the Scottish or the Welsh, but if they do, then I suggest that they spend some time reading up on the Peterloo massacre or the Tolpuddle martyrs or the 80's miners strike.
Then again I'd hate for reality to get in the way of any thinly veiled Anglo bashing.
