The Celts are not the master race. That's what it's measuring. Even outside of Ireland the area lit up in Spain are the Catalonians, a Celtic people. Why did they fall to the Romans? Why did they fall immediately after the Romans fell and get replaced mostly by the germanics? Why do Catalonian politicians favor socialism more than the rest of Spain? Why do people with Irish heritage in London commit more stabbings and why are they typically part of the working class? Why is it that poor white Appalachia is more Irish than the rest of the US? The stereotypes of Irish and gingers, common in England, are accurate. Think of the Weasley from Harry Potter. They are disorganized, drunk, emotional, breed before they have security, and have messy homes in disrepair. They are also annoyingly high pitched. They are hill niggers.
