Yes so according to you the Catholic Church condemned her own teaching for hundreds of years. No the very fact that Vatican 2 contradicts Catholic teaching should give all true Catholics pause. Instead there are those who prefer to condemn those Catholics who recognize that the Catholic Church can’t contradict herself.
But Pius XI is very clear what constitutes anti-Semitism. Others (like yourself) call Catholics anti-Semitic or "bigoted" when they are merely showing that they believe and profess the Catholic Faith as it was taught since the beginning of the Church.
I once believed that Nostra Aetate was Catholic when I converted from .... the Jewish faith. It is not. It is not a "development" because it contradicts prior teaching. The Catholic Church can not contradict what it has always taught.
