Except that more Welsh people voted for Brexit than Remain. Please stop trying to make this about regions. It's not. There are plenty of people in England who are just as fucked off with this as you are, just as there are plenty of people in Scotland who voted Leave.
Scotland isn't a region though: it is a nation that has its own parliament, which is being ignored by Westminster, with separate legal and educational systems etc. Therefore the views of its parliament regarding the Brexit legislation are important since the Scottish parliament is considered to reflect the views of its electorate and one aspect of this is a rejection in Scotland of both the Tory party and Brexit in both Holyrood and in current Scottish representation in Westminster.
FPP elections and referenda, where the 2016 result in Scotland was notable, are crude methods but by any standard the 2019 GE result, bearing in mind the context, indicates that Brexit is happening because it was the desire of the majority of the English electorate in 2016 to the extent that last year a substantial number of voters in England switched allegiance in order to support Brexit - and in Scotland, where the Tories campaigned on the basis that a vote for them was a vote against Indyref2/independence, lost substantial ground. Therefore the 'United Kingdom' isn't 'united' at all and the political mismatch between Scotland, and to a lesser extent NI, and England & Wales, seems to me to be firmly established now to the extent that the UK is untenable in the longer term if the electorate in England continue to support the Tories.
My hope, for what it is worth, is that Brexit (which won't be 'done' this month) will be the monumental fuck-up it promises to be, and that perhaps as 2020 progresses and the risk of 'no deal' in December grows, that this reality will force the political agenda in ways that encourages the break-up of the UK: food shortages and price rises, negative effects on jobs and employee rights and problems with goods moving to and from NI all look like potential problems - and that is without the risks of a closer trade relationship with the US.
Perhaps it may even be that the very people in the English regions who were naive enough to jump on the Tory bandwagon last year so as to let Brexit happen will be the very ones making the most noise once the penny eventually drops. For things to change so as to either get Brexit into safer hands and/or break-up the UK we are now dependent on the incompetence and intransigence of the Tory government - so we at least have a chance.
