Many Jewish groups have raised the anti-Semitism alarm. Having been born of a Jewish father and a Catholic mother, perhaps I can offer a more nuanced view. Personally, I have never heard of Replacement Theology. Like all Christians, I was taught that Jesus brought a New Covenant to replace the Old. Evidently this belief has now been classified as hate speech.
Religious tolerance is essential for America's survival.
But the JDL and other Jewish groups seem to have misunderstood its meaning. Tolerance does not mean changing everyone's beliefs to match yours. I know about religious hatred. It divided my family for years. When my mother became engaged to my father, she worried that her Jewish in-laws might dislike her for being Mexican.
