Perhaps a look at the structure of Turkey might clarify things. The country is trying to become a modern secular society to support its application to join the EU, but the vast majority of people there are deeply religious and reject what their government is trying to do. The only mass religion found there is Islam. I haven't found any report of this murder that mentions religion, but thishttp://www.independent.co.uk/news/world/...lf-1655373.html
help to substantiate what I have just said. In addition, I am not aware of any other social structure other than a Muslim/Islamic one that holds "honour killings" to be not just justified but mandated. Sure there are murders in all societies, but "honour killings" are a very special phenomenon associated AFAIK only with Muslim societies.
I am astonished at the inability of some to see what is going on, put it in context, and have a rational discussion about it. This is not remotely a "hate" thread, nor is it attempting to typify Muslims. It is however referring to a trait that is sadly too common in Muslim countries and communities-within-countries, and especially in Turkey.
