History of Islam in Eastern Europe is bloody and bad

Raymond Ibraham:

The 630 Year-Old Reason Eastern Europeans Dislike Islam

By 1354, the Ottoman Turks, under Orhan's son, Suleiman, managed to cross over the Dardanelles and into the abandoned fortress town of Gallipoli, thereby establishing their first foothold in Europe: "Where there were churches he destroyed them or converted them to mosques," writes an Ottoman chronicler. "Where there were bells, Suleiman broke them up and cast them into fires. Thus, in place of bells there were now muezzins."

Cleansed of all Christian "filth," Gallipoli became, as a later Ottoman bey boasted, "the Muslim throat that gulps down every Christian nation — that chokes and destroys the Christians." From this dilapidated but strategically situated fortress town, the Ottomans launched a campaign of terror throughout the countryside, always convinced they were doing God's work. "They live by the bow, the sword, and debauchery, finding pleasure in taking slaves, devoting themselves to murder, pillage, spoil," explained Gregory Palamas, an Orthodox metropolitan who was taken captive in Gallipoli, adding, "and not only do they commit these crimes, but even — what an aberration — they believe that God approves them!"

After Orhan's death in 1360 and under his son Murad I — the first of his line to adopt the title "Sultan" — the westward jihad into the Balkans began in earnest and was unstoppable. By 1371, he had annexed portions of Bulgaria and Macedonia to his sultanate, which now so engulfed Constantinople that "a citizen could leave the empire simply by walking outside the city gates."

In the years following the battle of Kosovo, the Ottoman war machine became unstoppable: the nations of the Balkans were conquered by the Muslims — after withstanding a millennium of jihads, Constantinople itself permanently fell to Islam in 1453 — and they remained under Ottoman rule for centuries.

The collective memory of Eastern Europeans' not too distant experiences with and under Islam should never be underestimated when considering why they are significantly more wary of — if not downright hostile to — Islam and its migrants compared to their Western liberal counterparts.

Islam's bloody history of conquest appears to be erased from the memory of many in the West, but those whose ancestors suffered under Muslim oppression have a long memory.  The rest of the world would be wise to listen to their experience.  There seems to be an effort in the West to suppress this history.  Muslims were recently successful in getting a lecture by Ibraham at the US War College conceled because they did not want the US military commanders to hear the truth.
