Of course they have a right. I'm not arguing that.
Replace them in your mind with displaced Icelanders and see how silly the article sounds.
BTW people in North Africa and parts of the Middle East (including Palestinians) are considered "white people" in the US (but apparently not elsewhere in the World like Europe and Asia where white seems to be synonymous with "European". I have Syrian, Lebanese, and even Iranian friends and they are considered white people.
It seems Europeans/Asians have long seeded continent/racial issues. So that makes this article even more of a quirky read when it focuses on "white people" and we scratch our heads.
"White Westerners, white Americans in particular, are a thoroughly vassalized, deracinated people."
^^^Definitely European/Asian racism on display here.
