Overall, Geert Wilders handled his position pretty well, with the Muslim callers coming across as pretty disengenuous and lacking any substance to their message. But one thing the Tundra Tabloids would take issue with, concerns violence perpetrated by other religions and the taking of holy scripture literally.
The literal interpretation of Islamic texts have been given a seal approval by all the known orthodox schools of Islamic scholarship and jurisprudence. Events recorded in the Bible however, are only a descriptive accounting, in contrast to the Koranic proscriptive reading of events recorded in its pages. The call to spread Islam by the sword (just look at the flag of Saudi Arabia) is an open ended one, which greatly differs to the reading of the ancient Hebrew texts. KGS
