I've lived here for about 34 years, which is the vast majority of my adult life, I have no wish at all to live anywhere else in the British Isles. Pride doesn't enter into it but Scotland's politics are a closer match to my own than most of the rest of the UK. The weather can be a bit sh!t if you like cycling & motorcycling but I'll take that.
Read about the Darien Scheme, which was a financially ruinous attempt to colonise Panama in the 1690s, backed by a bunch of rich Scots investors to the tune of about 1/5 of Scotland's entire wealth. Out of the 40 signatories to the Act Of Union, around 30 were Darien investors, who received full reimbursement for their losses as recompense for signing away Scotland's parliament. This is the subject of Burns' poem 'Parcel Of Rogues', which the 'bought and sold' quote comes from.
From this latitude it looks like the Welsh independence movement is healthy and growing fast, and I doubt it'll be discouraged at all by the obvious disdain and contempt for the devolved nations being demonstrated by the UK establishment.
Top tip for you - attempting to use words like 'immigrant' as an insult or attack line does have the effect of making the user come across like some sort of disgusting blood-and-soil racist scumbag. You don't want to be that guy, do you?
