Europe is in the midst of disaster, only, they do not realize.
On the issue of the right to insult the religious beliefs of others (and most religious believers are peaceful), then people who organise activities like this one in Texas put legislators in a very difficult situation. They force them to choose between security and freedom of speech. I hope they don't repeat this kind of stunt for the sake of the security of the silly people who turn up to them, and also for the sake of freedom of speech of many people, which they are jeopardising.
The response to and speed of neutralising the attack is a lesson to Western European countries when these free-speech events take place.
Of course a more sensible route would be to consult Muslim groups and even ask them to contribute to such event so that offence can be minimised and positive relations between different groups can be strengthened. If the group in Texas had made this kind of effort, then this incident would probably have been avoided. Unfortunately, they think Muslims are bad people and deserve a good kicking.
“Muslims are the vilest of animals…”
“Show mercy to one another, but be ruthless to Muslims”
“How perverse are Muslims!”
“Strike off the heads of Muslims, as well as their fingertips”
“Fight those Muslims who are near to you”
“Muslim mischief makers should be murdered or crucified”
