I think Glenn Greenwald corrects Bill Maher's political and religious bias. All Abrahamic doctrines are equally dangerous. Maher's political bias is found at the very beginning where he says "it's not our fault" referring to the fall of Iran's Shah and the rise of religious Khomeini. His opinion is the Western official narrative lie. At 2:00
after he interrupts another panel member and says "..that silly liberal view that all religions are alike...", he reasons only with a few past decades, when instead the West, the world's GNP heavyweight, has controlled the Middle East's Oil for a century using war and concludes with the Christian-Judaic Western narrative that Islam is, therefore, more dangerous. It's Christian and Judaic Western imperialism that drives the violence in the Middle East and makes it appear Islam is the most dangerous religion. Of course, all three Abrahamic doctrines are equally dangerous.
Unfortunately, Israel has subsidized Orthodox Judaism for five decades which sets Israel on a path to become a much more religious, and therefore, dangerous nation. See http://www.takeoverworld.info/pdf/Engdahl__Century_of_War_book.pdf
