I just scanned through the paper and here's a quote:
With dashed hopes and a loss of faith in the Weimar Republic, fury and despair were channelled
into the ranks of populists and demagogues, with the Nazi party campaigning against austerity
and offering promises for a new era of prosperity.
So, it's not nationalism rather people getting angry against the government which failed them. Any party can then shape the agenda and turn it towards nationalism or a particular community while promising prosperity.
Consider old school New deal socialists or paleoconservatives. If you told those guys that honest married black men were out of work and couldn't support their families, they would be concerned. Seeing it as their duty to do something.
Compare that with Ayn Randian Libertarians who generally think that the destitute should just up and die already. And Hayekian neoliberals that think that's simply not their problem.
It's the above attitude that leads to fascism and communism. They become dominant when the social leaders abandon any sense of duty. It's very scary because that's the exact situation in the US currently.
