If you see Jews as a group that must be opposed that means you are an αnтι-ѕємιтє. When I say that I am anti-abortion it means that I am against abortion. When I say I am anti-pornography, it means I am against pornography. To be an αnтι-ѕємιтє means to be against Jews. If you see Jews as an evil to be opposed (as I see abortion and pornography) then you are an αnтι-ѕємιтє.
Opposition to their collective action. If someone pretends they do not act collectively, and that these collective actions are not often harmful and in fact directly opposed to Catholicism, then there is a problem facing reality. (from what I've seen)
I am not talking about recognizing that Judaism is a false religion. Judaism rejects Christ and is a false religion. It is therefore evil as all false religions are. But believing that Jews as a race are an enemy to be opposed is anti-semitism.
Well, they do to a large extent constitute a "race" in the sense that they have a common origin and genetic similarities. But they are not opposed because they are a race. If they become true Christians then there isn't a problem.
Even if what you believe about Jєωιѕн power were true, seeing Jews as an enemy to be resisted means you are anti-semitic.
It all depends on how antisemitism is defined.
If I were to think the Jews are a biological pest like the nαzιs, that's a great deal different than thinking they have a certain character, organization, ideological tendency as a people.
