Not so.
There is only one non Arabic reference to Mohammed during his lifetime.
(If it is the same Mohammed).
All that is stated is that he was an Arab king.
Or whether or not you know anything about ancient near eastern history, more like.
"There's probably quite a few folks here that would take offense to your claims on Moses."
I much don't care whether islamists think I am insulting a successful 7th century brigand, and I don't care whether our own home-grown literalists are upset that I don't believe their fairy tales about their King Arthur. They can take all the offense they like. Truth isn't an opinion poll.
While on the subject, I wish also to address those fine upstanding tinfoiled kooks who have convinced themselves there are grand satanic conspiracies at work, and secret powers ruling the world. I am sure plenty of silly people think that of Islam. I am not surprised, when Bob Jones thinks it of Catholics, and Pat Robertson thinks it of Masons, and Lyndon Larouche thinks it of the British royal family, and others nominate - the Federal reserve, the UN, the CFR, the communist internationale, elders of Zion, and for all I know the orbital mind control lasers.
Give Bin Laden and company a little bit of credit for sanity, though none for justice. At least when they challenge the governing power in the world they manage to find some of the right street addresses. The US military actually decides who runs the world, taking immediate direction from the pentagon, political direction from the white house and capitol building, based on wealth and technology created by American capitalism. Those of us who consider that a Good Thing (TM), bother ourselves about seeing that the US military is used reasonably justly, as well as effectively.
Those looking around for guys with horns hiding under beds presumably bother themselves about other things...
