Well, I'll make it clear that I'm not pro-Jew or anti-Jew. I am for justice and fairness and while I wouldn't necessarily accuse you of blatant antisemitism I would suggest that you are making subtle implications of Jews as a whole and their defense. I am one of the most anti-religion person I know, however labeling an massive sector of the global population unfairly is simply unjust. Perhaps you weren't explicit, but I clearly got that sense from this whole thread and didn't like it. I know many Jews, some cultural and some religious, and all of them would consider ritual sacrifice horrid.
As for your argument that you accuse Jews of protecting the sacrificers, again my point hold. I can't argue it didn't happen because I don't have any insight on that, all I know is the word Jew should be stricken from your vocabulary on the subject. At this point, we now know it was Jewish people who did it, perhaps even in the name of their Judaism, but today none of that holds true in any appreciable way. Basically, you can have the most cogent argument for specific cases or conspiracies, but you cannot insinuate an entire ethnic group is culpable.
