Mrs Didactophobe and I visited it several years ago. It clearly was a beautiful city at one time, but in recent decades has been allowed to descend into being a sordid cesspit of perversion: prostitution, drugs, pornography etc etc etc.
Sadly, a large number of Dutch protested yesterday against Geert Wilders' film, Fitna. Is the film any good? Who knows? The nutters attending the demonstration yesterday hadn't seen it; nor has anyone else, since it has not yet been released. However, if the Netherlands really is a tolerant society, it should value Wilder's freedom of expression sufficiently to allow this film to be shown.
What has happened, of course, is that people worldwide are terrified of Islam. They know that it is too often used as justificatin for violence and murder. Yet, what has happened in countries with Shari'a law? In Afghanistan, the punishment for sodomy used to be the sodomites having a wall bulldozed on top of them. In Iran, the official line used by Ahmadinejad has been that there are no homosexuals in Iran. As the rest of the world knows, homosexuals in Iran are routinely executed. Do these ultra-liberal Dutch people want to see Shari'a law in Amsterdam? There would be a lot of harm caused to a lot of people.
Moderate Muslims will not want any harm to come to Wilders. They follow the precept from the Qur'an that there is no compulsion in Islam [Surah 2:256]. Anyone who believes this will accept that, therefore, there is no need for Wilders or anyone else to avoid insulting Islam.
