You do that at the once in a lifetime referendum
Even the most hardline ultra British nationalists/tories don't say this.
That's nothing short of totalitarianism.
and the rest of the time you put independence to one side vote for the party that you think can do the best job of running the country
Put to side for a moment our individual views on this- it is clear that for many voters they see independence as the route to the country being run better. You have every right to disagree with this view. But are you saying these people don't have a right to their view?
The fact that so many people genuinely believe that the SNP is the best party to govern Scotland, despite its numerous major failings, is very worrying
Again, people are often voting for the SNP, not as an endorsement of their policies but as a show of support for independence and because they see no better alternative.
Where does your faith come from to be so sure that Labour in Scotland would be any better at policy delivery?
Don't you remember the mess they made of the parliament building?
Their first minister resigning in shame?
The Scottish Tory leader also resigning due to a financial scandal?
Scottish Labour built zero mainstream council houses in Scotland from 1999-2007 when they were in power. They brought in uni fees.
They built school with PFI money that was a huge ongoing waste of taxpayers money.
They closed countless schools and hospitals.
I'll give them some credit that they had some good policies like the Breastfeeding Act and eradicating unintentional homelessness.
But they made lots of mistakes and didn't deliver some devolved utopia.
