It's European culture and history that shaped the U.S. And Islamic civilization shaped European history to a large extent. Although they have done their utmost to conceal this reality, they certainly do NOT teach any of this at schools. I have some very good books on this issue in my library. It's amazing how much they lie about history without shame.
In the Top Capi museum they still have letters from Queen Elizabeth pleading for help and protection during their battle with the Spanish Armada. There were three main powers in the world, and all three Muslims: Sultan Sulaiman Zeeshan of the Turk Caliphate, the Mughals of India, and the Saffavid dynasty of Iran/Khorasan. The West doesn't like those chapters of history at all.
According to them, Muslims just learnt everything from the Greeks, had no literary or scientific contribution, and made no advances. Even though Muslims had breakthroughs and excelled in every area of science. From mathematics to the humanities - Ibn-e-Sina's 14-volume Al Qanoon fitt Tibb, served as a chief guide to medicine, being taught in every major university and learning center in Europe from the 12th to the 17th century - what other piece of writing has stood the test of time for FIVE centuries. The West doesn't acknowledge Muslim contributions, but everything from the word Admiral(Ameer-ul Bahr/Ameer of the Seas) to geographical places like Gibralter(Jabr-ut-Tariq, after Tariq bin Ziyyad), to the very numerals(1-2-3), are Muslim.
But the Islam of then is pretty different from the Islam we see now. These days, people are so rigid and have their egos invested in what they are saying. In the 10th century, it was the norm that scholars would begin their debate/discussion with this statement that said, to the effect, that what I am saying might be wrong, but this is what I have seen so far. No egos and personal attacks just because a person had took a different perspective.
And in the medieval era, extremist Christians who wanted to become "martyrs" would come to Muslim lands and publically say the worst profanities about our Holy Prophet(PBUH), knowing that it was a very serious crime to do in Muslim lands. They wanted to become "martyrs" and then their hanged/dead bodies would be taken back and paraded through Christian cities to rile up the masses for yet another Crusade. And the Qazis would not summarily hang them, like the Muslims act now. They would repeatedly request and give them chances to recant what they said. Those who recanted were not punished.
Muslims had such a different way of governance, that when Abu Ubaidah bin Jarrah recieved an urgent communique from Khalid bin Waleed, ordering him to immediately head out to Yarmuk(for the decisive battle against the Romans, where 40,000-strong Muslim army was surrounded in the Yarmuk valley with a combined Byzantine force of over 200,000), he headed out of Hammas and Bulvak and returned the Jizyah collected, back to the people saying the Jizyah obligated the Muslims to defend the townfolk, and Abu Ubaidah did not know if he would be able to fulfill that obligation now. History records and documents the Christian patriarch of the town as having publically prayed for the return of the Muslims, saying their lives were better under Muslim rule than under the rule of their own fellow compatriots. The West paints a deceitful picture where Muslims were oppressors bent on waging wars and conquering all. They fail to mention that the two superpowers of the time, the Byzantine Romans and the Iranian pagan civilization initiated hostilities against the Muslims first. And both these civilizations were excessively cruel to the people they ruled, tying conscripted soldiers into chains so they wouldn't be able to desert or run, and how almost everywhere the populace welcomed the Muslims.
No-where were there any forced conversions, it is against Islamic law, and it is very hypocritical of the West of accusing Islam of "spreading by the sword". Especially because European nations waged wars all across the world decimating weaker cultures, from the Native Americans who fought with bows and arrows against Western cannons and rifles(not content with that, they also spread Polio and diseases for which the Native Americans had developed no immunity, never being exposed to them before - killing the vast majority of people inhabiting South America). To killing the Aboriginal people of Australia, colonizing in Africa and India. And despite the West's overwhelming military superiority, the natives in all these people desperately held on to their native beliefs - passing them in secret from father to son. Even with forcible conversions and the penalty of death imposed on anyone discovered practicing their beliefs, the culture sustains. When the West left, the native people went back to their old culture. The human spirit can overcome the worst kinds of oppression and tyrany, and still hold on. The West has centuries of proof that you cannot dominate the human spirit "by the sword", as their own repeated attempts have failed.
When Muslims came to India, so moved were the natives by the equality and justice of the Muslims, that Muhammad bin Qasim was thought to be a "Devta"(religious diety) by the locals. The local rulers imposed a strict caste system where if the lower masses did so much as have their shadow cast on a brahman, there was severe punishment. The Muslims believed that all humans were equal and wealth and birth did not make one superior to the other - it was the duty of the rich to be charitable to those less fortunate(zakaat and sadaqa), and five times a day for prayer, the poorest of the poor stood shoulder to shoulder with the richest, for Salat/Namaz.
The Islam we see now, is a consequence of Western colonization. Muslims grew decadent with nearly a millennium of leading the world, and they lost what made them great. In India, the British came as traders begging and prostrating in front of the Mughal king Akbar, and Akbar gave them space in India. The British increased their wealth and influence, and Akbar's descendant Bahadur Shah Zafar was imprisoned by the British and had all of his sons beheaded and their heads presented to the aged king in a silver tray, after he tried to evict the British from his kingdom. The Europeans displayed their high moral standards and humane practices everywhere else, from the Americas to China and Japan, they waged the deadliest wars mankind has ever seen, bombing civilian cities across Europe, eventually dropping nuclear bombs on two(it was considered immoral to harm civilians, and standing armies fought each other). Even in recent history, they've continued to come up with pretexts to attack one country or another, from Vietnam and Korea to Afghanistan and Iraq. The famous
historian John Pilger made a famous documentary about the West directly or indirectly invading over FIFTY nations in the past fifty years(and they always attack weaker/helpless nations, they never fight fair fights against an evenly matched adversary).
So - Western bias is not a new, or a surprising thing. Revising history, is one of the milder things they do.
