I wouldn't put too much weight on those statistics.. I think you are inferring too much from one study. Do you have a source?
So you don't even know what the source is but you're already telling me to dismiss the findings out of hand. You sound like a reasonable person.
My source is the University of Oxford:
https://www.migrationwatchuk.org/briefing-paper/385
Key quotes:
By March 2015, a YouGov/BBC poll found that 64% of people in Scotland wanted immigration reduced or stopped completely. The figure in the same poll for Britain as a whole was 70%
Furthermore, recent polls show that attitudes in England and Scotland on the importance of immigration as an issue facing the country are similar
However, by February 2016, an Ipsos MORI found that identical proportions of those surveyed in Scotland (27%) and in the UK as a whole (27%) named immigration as the most important issue facing Britain
However, the desires of overwhelming majorities of those surveyed for net migration to be substantially cut are all the more striking given there are only around half as many migrants per head of population in Scotland when compared to England.
Now unless you're about to tell me that the University of Oxford are untrustworthy shills, then I think you're wrong, and I hope you will have the intellectual honesty to admit that you are wrong.
The SNP is popular... so that means the Scottish are easily manipulated? That's kind of derogatory.. What party should they support to avoid manipulation?
Same goes for Brexit though, eh? People can be manipulated into inflicting pain upon themselves.
