Pure anti-white and black supremacy. Let's say the Britons who built Stonehenge had dark skin, how does that change anything? Those people are our ancestors, not the ancestors of people who came from the Caribbean and Africa. When we talk about our ancestors who built the UK, it still means they were our ancestors, whether they were black or not. You were in Africa, not doing a whole lot to be fair, but your ancestors were not in the UK.
