They genuinely believe if they get independence they will be a ginger haired, kilt wearing, deep fried mars bar eating version of Dubai within 5 years.
That sort of opinion is the lack of respect Scotland has to deal with politically and socially, why do you promote it?
Its been three centuries and the opinion is still as alive as ever, you think it will change after another century of utterly irrelevant politics towards us?
Somehow this desire is totally unfounded, that apparently the Union is always the best solution, but if it continues, Scotland will still be seen as the leech sucking on "Englands" phat loot (though in all reality is it is a really just the preserve of a few rich estates that like to call the London and the South east home).
If the referendum fails to garner a yes vote and the morbid together campaign get their choice, we will be subjugated to one of two most likely scenarios, the good scenario would be that Westminster continues its devolution and starts to modernise the union.
The bad scenario is that devolution ends in any multiples of ways they can do it and hide it under something else, Holyrood becomes bogged down in bureaucracy of a vivid nature, as the non-votable labour/cons and lib-dem's try to destroy the SNP.
Quite frankly the referendum is the only vote we have, the last two scenarios are something we cannot choose, then of course the main choice becomes...do you stay or leave the country as the likelihood of another referendum occurring any time after a no vote, is the definition of slim.
