What exactly do you by "discourse"? Do you mean that people didn't talk about Jews outside of Europe? That's just silly, and incorrect. There are numerous anti-semitic events around the world, like the lynching of Leo Frank in Atlanta, Georgia, in 1915, which helped to inspire the rebirth of the KKK, and the Blood Libel of Damascus in 1940. But I'll refrain from an extensive reply until you clarify what you mean.

A crucial non European anti semite was Henry Ford who published a series of anti semitic articles in his paper The Dearborn Independent. These were later collected in book form and were sold worldwide.

In Colonial America, colonies would forbid the landing of any Jews, and some would not even allow them into port to get fresh water. Roger Williams, hearing of one such vessel, sent them an invitation to come settle in the Rhode Island colony.

While European in origin, the colonies were already quite independent.

And of course the Muslims pressured the Zoroastians out of Persia. Brahmanic Hindus managed to annihilate Buddhism in its native country.
