They may be racist and/or nationalist, but you don't tend to get ethnic cleansing or organized genocides.
There is a long and complicated history in English speaking people of "rights for me, but not for thee" which started with the king, was broadened to nobles with the Magna Carta, was broadened to rich landowners with the establishment of Parliament, was in the process of being broadened to free white men around the time of the American Revolution and has piecemeal been given to other groups over time.
What today we consider "universal rights" were historically not universal. Our awful treatment of others is tied to our not granting rights to them. And our awful treatment of ourselves (for example in totalitarian societies) is tied to our being subsumed in something greater.
When a large group of your population is unable to financially afford justice that's a form of ethnic cleansing.
Genocide is horrible, but what could possible be more evil? Here is what: masterminding it so that a large group of your population no longer sees it for what it is and would rather point at another country for its concentration camps than solve their issues at home.

How would you describe the US private prison system, or gitmo if not "organized genocide"?
There are 39 prisoners in gitmo. In its total lifetime there have been 780 people. 9 died in custody. I wouldn't call that genocide.
> the deliberate killing of a large number of people from a particular nation or ethnic group with the aim of destroying that nation or group
Smallest genocide by death toll(killing of Tasmanian aboriginals by the British) killed just 400 to 1000 people.
