This article can be answered soon as you get to last paragraph.
It starts off discussing issue of honour killings which are barbabric no doubt, all the place where these killings take place the law of the lands is secular. Honour killing cannot be found in islamic laws or any texts nor is it permitted by islam.
So at end of article how can they attack the quran and islam in general when it is the non implementation of islam that allows such disgraceful things like honour killing to take place and criminal who do it get away?
what has quran got to do with honour killings? if it has nothing to do with it why is it included in the article?
