So if my parents were muslim I would be a muslim rather than a professed Christian?
Sorry Raycpa, I am not an expert on those subjects.
I think that it's important to distinguish whether we're talking about what all Muslims believe and what the Jihadi's believe. To a Jihadi if you are born to a Muslim you are a Muslim and if you grow up and become a Christian you are apostate and subject to death and any "believing Muslim" is ordered to try and kill you.
Within immigrant Muslim families in Europe, the US and, most recently that I've seen, in Australia, there have been several stories about "honor killings," mostly of daughters and often for being too "promiscuous," specifically fraternizing with non-Muslims. However, the Australian incident I mentioned from a couple of weeks ago was a case of a father attacking and attempting to kill his daughter for saying she didn't want to be a Muslim. He apparently ripped the cloths off of her then cut her severly with a knife in the insuing struggle, while her mother tried to protect her. The mother was killed and I believe that the father was not expected to live from injuries himself, though I'm not sure how he got injured.
