therugratef, the thing is though: Western European society has never had the same concept of family/clan honour as traditional Arab societies - it's a tribal thing originally AFAIK and has many other manifestations too (affecting both sexes).
Why is there not more of an outcry about Arab wife killers? I'm thinking because "we" do this too and would hence look slightly hypocritical if we protested too loudly. And that's where the whole thing gets slightly racist IMHO. Because it implies that killing women for not adhering to the rules is only really a problem when it's the "others'" rules, so to speak. Our rules, i.e. that partners, not blood relatives, have their 'honour' or 'pride' at stake WRT women's behaviour, are totally okay, of course. Totally hypocritical.
Don't get me wrong: "honour" killings are despicable. I just have a major issue with people who otherwise couldn't care less about women suddenly turning into ardent feminists where the women of differently coloured men are concerned.
