And depending on the context - not even a slur.
Seth Rogen and Sarah Silverman just called a white guy a goyim on their show on HBO Max.
That could also be a slur... but nobody is making a federal case out of that!
Singular: goy.
Plural: goyim.
(Just like the good ol' English words "cherub" and "seraph.")
Regards,
Because white men aren’t whiners, and no one cares what those two pieces of trash think.
