I have to disagree fully there. Part of the reason Scotland wants to remain in the EU is that their economic future depends on immigration. It's hard to see that as tribalist, much less xenophobic.
With respect I think that is neither here nor there, and doesn’t hold water as a justification of Nationalism. The SNP did not arrive on the political scene in response to Brexit, they have been growing in influence for decades.
Nationalism is by definition predicated on an appeal to tribal sentiment and identity politics. To say that the SNP is a world apart from the EDL may seem like a convincing statement on the face of it, but I’m not sure if I am convinced. It looks to me like a case of same ****, different bucket, as they say in Australia.
English Nationalism, on the rise since the collapse of the world banking system in 2008, makes me feel deeply uncomfortable. The fact that Scottish Nationalism wears a modern face doesn’t make me any less uncomfortable.
