Here is the lowdown on the Jews or "Jews". Very few Jews are Semitic people. The few that are Semitic are the Mizrahi Jews who come from parts of N. Africa and the Middle East. Most true Semitic people are the Palestinians, Arabs, Ethiopians (to the surprise of some), etc.
The Ashkenazi and Sephardi Jews are not Semitic people; and Sephardim being "Semitic" is a misnomer in the Gentile world, and it is a perpetuated lie in the Jew world, that is, the ones who are making the claim they are "Semitic." The misnomer that Sephardim are "Semitic" comes from the fact that their liturgical practices and rituals are almost, if not entirely, the same as the Mizrahim, but that is where the parallels end. The ethnicity of both are different. Again, the Mizrahim are mostly Semitic, but the Sephardim stem from Spain and Portugal, (and scarcely from Italy). The Ashkenazi / Khazar Jews stem from Germany, eastern Europe and central Asia (such as Georgia - the origin of the Khazars). The Ashkenazi (Khazar) Jews' liturgy and rituals are very much different than the Sephardim and Mizrahim. It must be noted that Sephardi(m) is the actual name of a liturgy (or ritual) that even the Mizrahim reference as the name their liturgy, therefore, the origin of the name "Sephardi(m)" is not based on ethnicity, rather, it is liturgical; but again, although the Sephardim and Mizrahim use the same liturgy, they are different ethnically.
It also must be noted that Jewry is more of a nationality - a citizenship, or even an ethnicity, rather than a religion. This includes all of the Sephardim, Ashkenazim (Khazars), and Mizrahim, despite some being actually Semitic and most not being Semitic. Ask any Jew if being a Jew is more about nationality/citizenship/ethnicity, and most, if not all, will confirm it is true. That is why most Jews, whether they are practicing Jews, pagans, New Agers or atheists, work with each other to advance the anti-Christ agenda in culture, government, judicial system, education, economics, etc. It is something that is wired in them. The only thing that can nullify such disposition of the Jews is if he or she accepts Christ's death and Resurrection, and accepts Him as Lord and Savior.
Now, the Jews (or really "Jews") are not true Jews; and Judaism is not the religion and spirituality of Joseph, Mary, Jesus, John the Baptist, and the other descendants of David. Instead, Judaism is a religion based largely off of rabbinical discourse and writings that occurred after Our Lord's Resurrection, and is recorded in the Talmud. The Jews ceased being real Jews the moment they rejected Jesus Christ, because Jesus Christ fulfilled the Judaic Law and prophesy. So in rejecting Christ, they rejected the Judaic Law, therefore, they were no longer true Jews. The real Jews, today, are the Christians, who are the spiritual descendants of Abraham; and Christ's Church is the new Israel.
Jews cannot handle a goy being on their level and understanding their ways (and tactics).
Study the Jews.
Yes, I very much agree with a previous poster, the true Catholics must infiltrate the counterfeits and Judaizers, and defend and spread the true Faith. Employ conventional and unconventional tactics however the circumstance dictates. However, never allow such activity to diminish our relationship with Christ and His Holy Mother. Never allow this warfare to diminish our lives in the Holy Ghost. We cannot allow our spiritual lives to suffer, therefore, beware the fine line that can develop between defending or spreading the Faith and pride, or trapdoor that awaits us when we rely on our own will and "genius" rather Divine Providence, when employing such infiltration. We must pray and remain steadfast in Christ. Prayer (and fasting) is extremely important.
