So what conclusion is to be drawn? It is obvious to anyone with reasonable intelligence that this is not an isolated, unconnected sequence of events. One possible conclusion is that Islam predisposes Muslims to unprecedented levels of violence - in other words it creates an unprecedented community of psychopaths wherever it predominates. A more benevolent conclusion might be that it enhances the psychopathic tendencies of those adherents of the Religion of Peace (TM) who would have been predisposed to violence against Infidels in any case.
In either case it serves as a cautionary tale insofar as non-Muslims are concerned. If you offend a Muslim intentionally or otherwise, be prepared for Disproportionate Response. Normally I would be in favour of DR, especially when Israel responds to Palestinian scum-bags firing Qassam rockets into Sderot, but when Muslim scum-bags attack white middle-class Christians in Birmingham supermarket car-parks, then the gloves are definitely off.
Update: A most illuminating comment on my recent topic of Sudden Jihad Syndrome has just been received from Dr. Hector Muhammad McScooterpipe (lately of the Neasden Jihad McScooterpipes, and coincidentally a founding member of the North London Islamic Self-Criticism Association):
Prophetic words indeed, Dr. McScooterpipe. We will be monitoring the situation with keen interest.
