According to the Holy Bible and most scholars the Amalekites were Arabs from the Arabian deserts. But not according to the Jews!
Heres the answer why they hate us:

“Armenia is also sometimes called Amalek in some sources, and Jews often referred to Armenians as Amalekites. This is the Byzantine term for the Armenians. It was adopted by the Jews from the Josippon chronicle (tenth century, ch. 64). According to Josippon, Amalek was conquered by Benjaminite noblemen under Saul (ibid., 26), and Benjaminites are already assumed to be the founders of Armenian Jewry in the time of the Judges (Judg. 19–21). Benjaminite origins are claimed by sectarian Kurds. The idea that Khazaria was originally Amalek helped to support the assumption that the Khazar Jews were descended from Simeon” (I Chron. 4:42–43; Eldad ha-Dani, ed. by A. Epstein (1891), 52; cf. Ḥisdai ibn Shaprut, Iggeret)

“In 1839...the British missionary Joseph Wolff found it “remarkable that the Armenians, who are detested by the Jews as the supposed descendants of the Amalekites, are the only Christian church who have interested themselves for the protection and conversion of Jews.” Scottish Missionaries Bonar and McCheyne suggested that “the peculiar hatred which the Jews bear toward the Armenians may arise from a charge often brought against them, namely that Haman was an Armenian, and that the Armenians are the Amalekites of the Bible” for becoming the first nation to adopt Christianity in 301AD. Late in the nineteenth century Joseph Judah Chorny reported hearing from the Jews of Georgia, among whom he had traveled, of their ancestral tradition that the Armenians were descendants of the Amalekites, and another Jewish traveler reported a bizarre practice in eastern Galicia, whereby the Armenians that did business with the local Jews would mourn Haman’s death every Purim, and light candles in his memory.”
"When in late 15th century R. Obadiah of Bertinoro,a native of Umbria who emigrated to Jerusalem,described the city's [Christian] sects in a letter to his father, he listed "the Latins, Greeks, Jacobites, Amalekites,Abyssinians." Armenians still hold their own quarter in the Old City of Jerusalem to this day.
The book Holy Women of Byzantium: Ten Saints' Lives in English Translation By Alice-Mary Talbot speaks about Byzantine Emperor Leo V the Armenian who ruled from 813 AD to 820 AD until his assassination by one of his top generals, Michael the Amorian. When describing Emperor Leo the book claims, “He is called Amalekite, meaning Arab, because of his apparent approval of Islamic prohibition of the depiction of sacred images.”
