Double standard? I don't understand what you mean.
What I am talking about is that the way Christianity and Islam preach you should react to attacks like this are entirely different. Hence the different reactions. So you can't say "why do attacks on Christianity not get the same reaction" - because the answer is obvious.
There is no excuse; but there is a reason. :)
Here's an example which might help show my point: there is a difference between the way a "religious" Glasgow Rangers football supporter and a Bath Town supporter will react if you call their teams sissies (i.e. the stereotype Glasgow guy would punch you in the face while the Bath guy would ignore you).
(EDIT: I realised that is a very UK centric example. Insert any sports team with religious and fervent followers for Glasgow and one with passionate but reserved followers for Bath)
EDIT2: if you wish to downvote feel free; but it would be interesting to hear why you disagree (this is based on observation of the two religions so I could be wrong)
The violence associated with football in Glasgow is literally religious - it's an example of Christian sectarian violence.
Attacks on Christianity don't get the same reaction because in most places it's the dominant religion, but that's not to say there's not violence associated with Christianity. The history of Northern Ireland is more complicated than simple religion, but that is an important aspect of the Troubles.
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.
I see what you mean (and I do agree; Islam possibly gets the most "free handouts" of all the religions). But..
Why do this behavior need to be taken on other terms than personal responsibility and the norms of civil conduct?
Clearly on a personal level their actions are their own responsibility and decisions - and are wrong.
But on a macro level there is just a reason why Muslims react this way and others don't. I think it's important to actually set out those reasons because somewhere in there we may begin to find a solution.
The attackers were swedish citizens.
This sounds exactly like the excuses and double standards I was refering to: "There is no excuse, but [insert excuse]."
