While on the topic of antisemitism, my son who got back from spending about a month in various Ukranian towns said the other day "thank G-d for antisemitism!".
When we all looked at him in puzzlement, he recalled how upon arriving at a certain town, a lady screamed at him and his partner "go back to Israel, this town has no place for Jews". My son responded by telling her that prior to WWII this town was 70% Jewish, and you are living on top of the blood of thousands of Jews that were murdered and their property stolen.
When he got to repeat that story to even the most disenfranchised Jew in the town, it brought about a Jewish awakening, prompting them to want to do a mitzvah to show their Jewishness. The other good thing about antisemitism is, that it protects from assimilation.
