There is this cultural problem of honorary killings.
in Sweden there have been a number of well published cases - one invilvong a woman who were quite famous (dunno if she wrote articles or not). She even had police protection for a while, but ended up being killed by her family because of honour.
Without attaching this to any particular religion, one has to concede that this behaviour is spawned largely by two factors; religion and the culture (which of course is heavily affected by religion).
And, as Hortlund points out, this behaviour is spreading to our countries. We're unable to defend ourselves since we cannot legally own handguns and police cannot defend us because they cannot keep a 24h a day watch.
So what we're seeing is an integration of immigrants. That is a huge problem in the Scandinavian countries and the blame is not solely on politicians - many immigrants do not wish to be integrated and hold dearly on to their own cultural values. This is not a problem as long as they're not breaking the law.
Unfortunately, Islam as it is practised in various Islamic states in the world today is quite misogynic and often treats women like property. When a young woman tries to fit into her new adopted country her family will react - sometimes with lethal consequences. The *justification* for such acts is often found in religious texts.
It's worth noting that Christianity had the reformation which by large modernized Christianity. For Islam there hasn't been such a process yet. As it is practised today, there are more 'problems' seen from a Western perspective in Islam (problems meaning problems with our ideals of democracy, freedom, equality etc) than there is with Christianity. The latter has more or less adjusted to the democratic values, whereas the former has been more sluggish to do the same.
