You wouldn’t say that about any slur you’re familiar with
I can imagine a kid named Nerus (https://en.wiktionary.org/wiki/%D0%BD%D0%B5%D1%80%D1%83%D1%81%D1%8C ) or Moskal (https://en.wiktionary.org/wiki/%D0%BC%D0%BE%D1%81%D0%BA%D0%B0%D0%BB%D1%8C#Ukrainian ), for example, and see no problem here because it’s just a name.
