Dear Mr Drumthwacket, Since the Roman Catholic church teaches unbiblical practises, it should be no surprise that its catechism would state that Allah (from what I have heard an Arabic name which is the equivalent of Baal) is the same god as the God of the Bible. From the attributes given for in the Koran and those given in the Bible for God it is obvious that they are not the same.
By all appearances Amazon banned Drumthwacket. Drumthwacket was well read, analytical and anything but a conventional thinker. I found that Drumthwacket argued rationally and always provided substantial evidence in support of his points. That may have been his downfall with Amazon. On occasion he quoted extensively from source material in his commentary and thereby may have transgressed Amazon's guidelines.
Drumthwacket seems to have been well received by scholars with whom he crossed paths. In fact Robert Spencer cited Drumthwacket for personal thanks here, on March 26, 2008: http://www.jihadwatch.org/2008/03/low-life-people-like-that-must-be-totally-ignored.html
Others were not so pleased. There may have been some sort of partisan effort to have Drumthwacket banned toward the end of the 2008 Presidential campaign. I recall that Drumthwacket was then introducing evidence that then candidate Senator Obama' had a history of association with and mutual support of radical socialists, anti-Semitic Islamists and leftists, and that Senator Obama had links to corrupt Chicago politics. Not long before his postings were deleted Drumthwacket was racking up substantial numbers of negative votes and was a target of left-wing anger.
That would explain his banning here. Amazon may well have decided that the Islam forum was not the place to discuss partisan politics which aren't really relevant. (Which, by the way, is the problem I have with Robert Spencer himself. It's not that he"s opposed to Islam -- I am too, but for different reasons. It's that he gives the impression that if you're not as anti-liberal as he is, you're not a true believer. Tactics like this are counter-productive, and Lewis, Rushdie, Hirsi Ali, Warraq, and Fregosi never use them.)
