A few things before I get to the video:

1. The few seconds before the demonstrations start WILL offend Muslims.
2. The rest of the protest seems like straight forward civil disobedience to me - people shouting slogans.
3. Trying to offend people which the few seconds of the shown video clearly show as the aim is not the same as free speech.

I got the video from here where you can read the comments of other people who condiser the protesters in a different light to me.
