Again you are making not only a mistake but actually a crime against history. Just to compare crusade to Arab conquering Iberian Peninsula
First: The Muslins received calls from Count Julian and the local people’s rejection of Gothic rule, asking the Muslims to help them and save them. As stated by the Spanish historian, “If the Arabs had not interfered in the Peninsula’s affairs in 711 CE and put an end to this age of turmoil, the Goths would have inflicted unimaginable harm on Spain.”.
Second: many Jews and Christians held government positions in Andalus, it was considered as the Golden Age of Jewish history. The philosopher Moses Maimonides, (Musa ibn Maymun) who wrote the Guide to the Perplexed."Judaism probably welcomed the conquest of Spain by the Muslims in 711. With the Muslim conquest began a Golden Age of freedom and tolerance for Jews. They freely entered the fields of government, science, medicine, and literature." Spain was home to by far the largest and most brilliant Jewish community in Europe; elsewhere, the Jews were hounded and persecuted. "Islamic Spain is sometimes described as a 'golden age' of religious and ethnic tolerance and interfaith harmony between Muslims, Jews"Christian,Jews."
Third: Andalus was the bridge used by the Muslims to transfer civilization to Europe, the time when Muslims were ruling is described as the Cardle of Europian Civilization. This is a quote Wilhelm Friedrich Hegel (1770-1881), German Philosopher "Science and knowledge, especially that of philosophy, came from the Arabs into the west" . another from Victor Robinson (1886-1947) Author, Physician, and Medical Journalist “Europe was darkened at sunset, Cordoba shone with public lamps; Europe was dirty, Cordoba built a thousand baths; Europe was covered with vermin, Cordoba changed its undergarments daily; Europe lay in mud, Cordobas streets were paved; Europe’s palaces had smoke- holes in the ceiling, Cordoba's arabesques were exquisite; Europe's nobility could not sign its name, Cordoba's children went to school; Europe’s monks could not read the baptismal service, Cordoba's teachers created a library of Alexandrian dimensions.”. Another quote from Georg
Your problem is that either you are not trying or you do not want to understand history, and you think the current civilization is the beginning of human kind and that others did not contribute to the current rise and development.
