how the SNP get away without being held to proper account
If enough people in Scotland believe this, they will be voted out of power.
There could always be a neverendum 2022 however.
Only if people want one, and vote in a pro indy majority again.
If it wasn't Brexit it would be some other reason
This I agree with. I don't think anyone (except perhaps the ridiculous Scottish Resistance) wanted another referendum so soon. It is too soon, and the current polls of 50/50 are just too chancy.
But Brexit, is huge. As countries Scotland and.NI didn't vote for it. Yet their citizens opinion counts for nothing in this. The UK Scots narrowly voted to remain part of.in 2014 is no longer in existence. In 2014 Scots.were told.that to stay in the EU they had to stay as part of the UK.
The UK may have voted to leave, but two of the constituent countries of the union did not.
