北方人種
Tyndall had "deeply entrenched" biologically racist views, akin to those of earlier fascists like Hitler and Leese. He believed that there was a biologically distinct white-skinned "British race" which was one branch of a wider Nordic race. Tyndall was of the view that race defined a nation and that "if that is lost we will have no nation in the future." He believed the Nordic race to be superior to others, and under his leadership, the BNP promoted a variety of pseudoscientific claims in support of white supremacy. Those parties he controlled restricted membership to people of Northern European ethnic heritage.
