Many people in the West are afraid to confront the violent cultures that commit these and other atrocities; they are afraid to tell them that they must change their murderous ways.
Rather than admit they are cowards, and that they fear they will be the next victims of this kind of violence, these people in the West mask their fear behind multiculturalism, trying to convince people they are open-minded instead of terrified by a culture of abusive bullies.
In a comment to Karo-Kari, Part 2, Anticant hits the nail right on the head:
The complacent attitude of some modern 'multiculturalists' in the West towards these and other primitive barbarisms astounds me. Apparently any atrocity is considered OK by these folk so long as it's a cultural or religious custom.
Fortunately the British Raj was prepared to be more culturally imperialist: there's a nice story that when the advocates of Suttee [widow-burning] defended it as their cultural custom, the British commander-in-chief replied: "Very well. Follow your custom. We also have a custom. We hang those who kill unlawfully. So we will build a gallows alongside your funeral pyre, and when you have burned your widows we will hang you."
To turn your head the other way and pretend nothing is happening while innocent people are brutally murdered is all it takes to perpetuate the killing, and thus to be an accessory to the crimes.
Right on, Anti!
"It is not solely cowardice."
I stand corrected. Please see Anticant's comment to this post.
