I understand the reason that this strategy works and why moderates don't actively distance themselves from it. By keeping silent and vague they will benefit from the power that the threat of violence gives. In Denmark there are quite a few places where the police can't operate on normal terms due to the mentality exhibited in the video above.

What I mean by double standard and excuses is the tendency to always add 'reasons' when it comes to islam.

Why do this behavior need to be taken on other terms than personal responsibility and the norms of civil conduct? It's not like the attackers - due to their religious affiliation and reasons derived from this - lack choice.
