The problem is this broad characterization of a subset of Jews as "child-slaughterers". (And how quickly it went THERE!) He is complaining that we are conflating all Jews with these "child-slaughterers" and we are thus tainting the "decent Jews" with the evil of the "child-slaughterers". Leaving aside that HE was the one who introduced "child-slaughtering" to the conversation, and so casually as to present it as a self-evident truth rather than the blood libel it is, HE is the one who is conflating "child-slaughterer" with Jewishness, as though "child-slaughter" was a Jewish trait, but only in the not-decent, animal ones. He is the one creating the subset and labelling that Jewish subset as "Zionist", a term which is unequivocally associated with Jewishness. If he wanted to discuss "people who slaughter children" or "people who derive joy from the slaughter of children", he could just say that. And he would not find any on this thread. Instead, he assigns that trait to everyone who he identifies as "Zionist (Jew)".
Not only do I feel as though "Zionist" is term with no utility in conversation, it has become a racial slur.
