the g-slur? I won't say it in case it is a slur, is that the word the jews call non-jews?

That makes way more sense, I thought he meant gypsy. In either case he should just say the word, this site isn't for children.

Whether or not “goy” is a slur is pretty complicated. It has pejorative uses, and outside of a strictly religious context any non-Jew is almost certainly only going to see those pejorative uses. But strictly speaking it’s a Hebrew word that means “nation,” and isn’t any more or less offensive in the abstract than Jew, Arab, Brit, etc.

(To my understanding, the closest equivalent is “ummah” in Arabic, where the connotation is flipped: goy can refer to a Jewish person but typically does not, whereas the ummah typically refers to Muslim peoples as a collective but can also be a general stand-in for “nation” or “world.”)

I think he ment Gypsy and not Gentile.
