" Should we stop having elections in Scotland if it doesn’t matter what we vote for."
Certainly... if what is being voted for is casting aside a recent 'once in a lifetime' democratic vote.
" Scotland does respect democracy. It voted to stay in the UK in 2014 and it did stay in the UK. That is democracy."
I don't call abiding by a democratic vote for two years and then casting it aside at the first sign of change respecting democracy, especially when the vote was known to be once in a lifetime.
Democracy would be respecting the results of that referendum for the appropriate term.
"Scotland did not vote to give up any right over its future no matter what happens."
No one is making that assertion. However, the SNP doesn't have carte blanch to change its mind at every whim.
Scotland made a democratic vote and needs to honour the results of that democratic system.
