Cofty..I agree social justice does not depend on independence, its down to whether one believes that democracy for deciding your own governance can bring about a fairer society.
As a more socialist leaning country I believe we stand a better chance not withstanding it will take courage and time to build.
Nothing great and worthwhile for humanity was ever achieved by complacency.
I believe the snp will eventually fragment and that the socially concious people of Scotland will vote for better government than the status quo.
Best wishes.
