That is a specific group that violently hates YESHUA. You are at odds with Paul, who’s live for Israel was so great that he was willing to go to hell if he his people could be saved. Replacement Theology is a demonic doctrine.
You’re wrong, because Paul never said we should support the killing of children.
It seems your error comes from focusing on people rather than on actions. Contemplate this for a bit. I’ll explain more later if needed.
Replacement theology is a slur to describe covenantal theology, which holds to the position that God's people in the church age are those believers, Jews or Gentiles, who have accepted Jesus Christ as Lord and Savior. To equate covenantal theology with anti-Semitism is to ignore the numerous non-dispensational Christians who have been sympathetic to Israel and the Jewish people. The Calvinist Puritans and partially Calvinist Anglicans allowed the Jewish people to return to England. The Netherlands, ruled by Reformed Christians, gave full rights to Jews expelled from Spain and Portugal. The United States at birth passed a Constitution that prevented the Federal government from imposing a state religion and placed no religion based restriction on immigration. The first Jewish chief executive of a country in modern times was Benjamin Disraeli of Great Britain, a mostly Protestant nation. The Confederacy, predominantly Methodist and Baptist with an largely Episcopalian ruling, had a Jewish Secretary of State.
All of the denominations I have listed held to a covenantal theology, as stated in documents such as the Westminster Confession of Faith. Your equation of covenantal theology with anti-Semitism is not supported by the facts.
