LessMiss, on one hand you say that Scotland, as a small country, is "easier to control and manipulate" and claim that its Parliamentary system is undemocratic. On the other hand you say that it doesn't matter whether or not people in Scotland actually want a second chamber, but "you tend to hope that those in a position to implement have the knowledge and will to do what is best". So are you actually for grassroots democracy, or would you rather have decisions made by a political elite "with the knowledge and will to do what is best", because that runs rather against the grain of your apparent concern for a lack of democracy in Scotland?
You also say that "a smaller country" you would "hope to see a more direct link between the electorate and voter turnout". Based on what trends? Based on its geographical size or the size of its population? Some people have suggested that there might be a connection with either or both, but I'm not aware that its in any way proven, and others have suggested that high turnouts correlate with high population density, rather than the size, and though Scotland may be small, much it is still sparsely populated. There are more convincing arguments to be made along other lines - that proportional voting systems tend to encourage people to vote - but that's another issue.
I don't think the current Scottish system is perfect, but, again, what of Westminister - since that's the system it is currently tiered with? What democratic advantages does hereditary peerage offer ordinary people?
Yes, lots of talented people have left Scotland to work elsewhere - which is fantastic. I don't think any civil society should discourage people from seeking global. Many people return with new skills, which is great, and others settle elsewhere for good. I think that there's been a failure in the past to capitalize on the potential links between the Scottish diaspora and Scotland, which may be something which begins to change as Scotland begins to assert more control over its international relationships, something not really possible pre-devolution. So, do talented people move away? Yes, of course, not necessarily a bad thing, and it's part of the reason why Scotland would like to have more control over its immigration policy and attract more skilled workers and talented from overseas, which I think is great. Do I think that it is only the brightest people who leave Scotland, leaving behind a hapless nation of dull and dim people? No. I think that some bright people leave, some bright people stay.
As for UKIP in Scotland, earlier in this thread someone mentioned what percentage of the vote they last got, and its was tiny, around 2%. I'm not undemocratically denying that they did so, but I'm not worried about a surge of UKIP support in Scotland in the slightest.
As to the notion that you can't intimate that people's political beliefs are wrong - well I disagree, I think you absolutely can. Political beliefs are there to be explored and disputed, and defended and rejected. No one's political beliefs have to be treated as if they are sacrosanct, they're not a matter of faith.
