Today’s anti-Semitism is based on people having contempt for the medine because it can neither wage definitive war and stand up for itself after Hashem hands it victory, nor make peace because there is no peace to be made with the enemies of civilization.
The anti-Semite sees the medine as representative of all Jews, and he sees it acting like the nebach innkeeper of old who begs the poritz for a little more time. So, he sees the Jew as a weak shlimazl as well.
“Theological” anti-Semitism really only exists among a small minority of Catholic and Protestant notzrim who believe in replacement theology. They are not much of a danger to us – they are the rump NK of notzrus. The Westboro guys are just the loudest expressions of that ideology as are Pat Buchanan and Mel Gibson. (Al Sharpton and Jeremiah Wright are preachers in name only – they are really secular demagogues and rabble-rousers.)
We are our own worst enemies. We do not stand up for ourselves and we use golus as an excuse not to rock the boat. Decent non-Jews want us to rock the boat as Hashem wants us to do. The scum minority live in fear of us, as the Arabs in EY did for a few glorious months after 67 before Dayan let the Wakf have rights in Yerushalayim Ir HaKodesh, when we rock the boat.
