tell that to my wife - she accuses me (rightly) of being pedantic and overly logical when i don’t need to be.... sigh...
It’s absolutely necessary in this case to be pedantic.
Historical antisemitism is considered to be a special kind of evil, because of the motivation behind it. Jews have been persecuted because they refuse to give allegiance to earthly kings before God - many Christians are also persecuted on this basis, but with Jews there’s thousands of years more of it, and Jews have never had the strength-in-numbers necessary for self-defense in those situations.
So when some radical Communist who happens to be Ashkenazi claims antisemitism on the basis that he is a Jew, I reject that deceitful tactic. He doesn’t believe in God, and therefore the special type of evil in question cannot apply, no matter how malicious the attacks on him may be.
