What most interests me in this (from Wiki) is the part about "the rejection of a particular way of thinking about God".According to Langmuir, it is based on "total or partial opposition to Judaism as a religion—and the total or partial opposition to Jews as adherents of it—by persons who accept a competing system of beliefs and practices and consider certain genuine Judaic beliefs and practices inferior."
As the rejection of a particular way of thinking about God, anti-Judaism is distinct from antisemitism but historically, it has also encouraged the development of racial antisemitism, a racist ideology which was articulated in the 19th century. Some scholars have found intersections between theology and racism and as a result, they have coined the term religious antisemitism.
But I am also interested in this phrase: "total or partial opposition to Judaism as a religion—and the total or partial opposition to Jews as adherents of it—by persons who accept a competing system of beliefs and practices and consider certain genuine Judaic beliefs and practices inferior" except that I want to be able to talk about a position that is anti-Christian for the same, or similar reasons.
These are really topical, interesting, relevant and valid questions to ask. And I assume, and I validate, that anyone, Jew or Gentile, can ask such questions and talk about the issue without being (accused of being) antisemitic in the sense of wishing ill on Jews or seeking to harm them.
And Happy (belated) Hannukah.
