The modern equivalent of the word goyim simply means heathen. And Christians call plenty of people heathens and there's no difference. And it doesn't matter because it doesn't give you a better place next to God when you depart this realm if you announce that someone else us a goyim or a gentile or a heathen or Pagan or a sinner for that matter.
