MEMRITv has a clip of Lebanese cleric Abd al-Karim Fadlallah perpetuating the Islamist fantasy that Muslims were already settled in the New World before Columbus landed there:
The Arabic language, 200 years ago, was a universal language. It's interesting to note that when Christopher Columbus went to America, in what language did he speak with the Indians? It is said that the language they spoke with the Indians and I have indisputable documentation of this at home... The intellectuals among the Indians spoke Arabic. He took two Arabs with him, to serve as interpreters between the Spaniards and the Indians. He took two of them as translators. So you can imagine the historic and cultural value of Arabic. It's undoubtedly very important.
His is just the latest of an ever-growing trend toward "Muslim-izing" the early history of the New World. They include this oldie but a goodie from Saudi Aramco World. Or, this 2003 "editorial" in the Charlotte Observer:
It is important for the American public to know that although this political movement by Muslims may be somewhat new, Muslims have been a part of the fabric of this society, in some fashion, since before Columbus. Muslim explorers visited the West Coast long ago. Arabic writings have been found in some caves in California. The name "California" comes from the Arabic word calif, meaning ruler or leader.
There's also this recent government-funded fantasy about Christopher Columbus' navigator. However, my favorite by far is the Middle East Policy Council textbook that states that Arab Muslims became Algonquin "tribal chiefs" long before Columbus arrived.
If it wasn't for Little Green Footballs, we'd never know this was going on. However, all you really need to do is just Google "Algonquin Muslims" and explore the results.
This would be laughable if it wasn't so scary. After all, this is the kind of garbage taught in US-based madrassas. And it just so happens that one of the justifications for jihad is to return previously Muslim lands to Muslim control. Regardless of how wacky the story is, it will resonate with enough US-born Muslim children who are taught to see jihad as a justification for future acts of violence and intimidation on the US homeland.
