As we have less non-white people basically.
Not one mention of our genuinely welcoming hospitality
So, did you just not read the article?
Historian Prof Murray Pittock is wary of the term "'Scottish exceptionalism"... But he does say that attitudes in Scotland towards immigration are more favourable.
"There's been pro-immigrant rhetoric and that's increasingly borne out in the Scottish Social Attitudes Survey, which is more pro-immigrant. It's now more pro-immigrant than south of the border."
"Polling and other kinds of measures show that Scotland has a more positive attitude towards migration, a lower concern about things like small boats - which are naturally more geographically keenly felt on the southern coast of England - and a more positive attitude towards refugees."
Sir John also says the message of the party in government is very different in Scotland. The SNP is described as a "civic nationalist party", which says it welcomes people irrespective of birth or ancestry as long as they are willing to commit themselves to Scotland.
Yes, other (perfectly valid and relevant) factors are mentioned, such as different social fault lines, different population demographics and even the weather.
But to claim that the article doesn't mention Scotland being more welcoming just smacks of being desperate to find something to take offence at.
It'd be absurd to try and argue that Scotland is this perfectly welcoming place - exactly the sort of Scottish exceptionalism warned about in the article in fact.
And as to your "As we have less non-white people basically" claim, that angle is mentioned once and only once, and is only suggested as one factor among many. It's certainly not the core argument of the piece.
