That is a good question. Just where do your fellow Muslims find their sick ideas?
THE Hate propaganda comes from Nazis Germany where Arafat's uncle the head Mufti
Haj Amin Al-Husseini fled to Berlin and learned and trained in, thus forever influencing the Jihadists.
BUT, the true source goes back even further, like I said all roads literally lead back to Rome.
HOW you might ask?
Simple: they created the demonization and hate propaganda in their one world religion and hid the political authority behind the religious.
This RCC church in turn through synods created their hate propaganda and acts that Nazis Germany simply emulated.
Here's my evidence essay on the subject:
In 1939 the Nazis barred Jews from train dining cars.
The Church’s Synod of Elvira (306) forbade Jews and Christians eating together.
The Synod of Clement (535) parallels the law for the Re-establishment of the Professional Civil Service (Nazi Germany -1933) by disallowing Jews from holding public office.
The Third Synod of Orleans (538) inhibited Jews from showing themselves in the streets during passion Week. In 1938 the Nazis past a decree allowing authorities to ban Jews from the streets on certain days such as Nazi Holidays.
During the Synod of Toledo the Talmud and other books were burned. Similar book burnings were a regular event in Nazi Germany.
The law for the Protection of German Blood and Honor (1935)
parallels the Synod of Elvira (306), which prohibited intermarriage and sexual intercourse between Christians and Jews.
The fourth Lateran Council (1215) mandated the marking of
Jewish clothes with a badge. In 1941 the Nazis forced Jews
to wear a Star of David. So Christendom foreshadowed the
Nazis.
In 1222 the Council of Oxford banned the construction of new
synagogues. In 1938 the Nazis destroyed synagogues in the
entire Third Reich. Again Christendom foreshadowed the Nazis.
In 1279 the Synod of Breslau legislated for compulsory ghettoes.
In 1939 Heydrich also ordered compulsory ghettoes for Jews.
Again Christendom foreshadowed the Nazis.
The Synod of Ofen (1279) forbade Christians from selling or
renting real estate to Jews. In 1939 a Nazi decree mandated
the sale of Jewish real estate. Again Christendom foreshadowed
the Nazis.
The Council of Basel (1434) prevented Jews from obtaining
academic degrees. In 1933 the Nazis passed a law against,
"Overcrowding of German Schools and Universities" with
the same effect. Again Christendom foreshadowed the Nazis.
The Synod of Gerona (1078) forced Jews to make contributions
to the Church equal to that of Christians. The 1940
Sozialausgleichsabgabe enforced a special Jewish income tax
equal to the party contribution levied on Nazis. Again Christendom foreshadowed the Nazis.
"The Nazis 'did not discard the past; they built upon it. They didn’t begin a development; they completed it.' This fact makes
ludicrous any unqualified claim that the Nazis were the enemies
of Christendom. In actuality, they were in very large measure the
agents for the 'practical' application of an established social logic."
(Hilberg, R., "The Destruction of the European Jews" Chicago:
Quadrangle, 1961), and (Eckardt, "Elder and Younger Brothers:
The Encounter of Jews and Christians" New York: Schocken
1973, 12-14).
The roots of the antisemitic "established social logic" referred to above lie in the antisemitic potential of the NT. The roots of modern antisemitism lie in the pages of the NT. Without it the Shoah (Holocaust) would never have happened.
A Disturbing Fact:
On April 19 1939 in celebration of Hitler's birthday All Catholic churches in greater Germany hoisted the Swastica in Celebration.
The Holocaust; is in it's foundation in Christian AntiSemitism, but Nazism didn't die as we thought, as we see the "radical violent" jihadist learned their wares from Nazis Germany and has been like a new arm of that propaganda machine.
