Not sure what you're getting at. Bottom line is there are far far fewer Christian honor killings. Christian Arabs are the only Christians to do them, but nothing like the numbers of Muhammadans. So I blame the influence of Islam and the culture it spawns
I've met christian men from Africa that refused to speak to me or sit next to me because I was a married woman. I was a christian at the time and my husband was there with me, but their culture is different.
I'll never forget one mentioning that he was looking for a wife and basically asking where he could find a good christian woman to marry. He wasn't speaking with the idea of dating her and getting to know her...but he was interested in an "arrangement."
All I could think of was that he was in for a real suprise!
The culture was key to the creation of the religion. Mo combined a whole bunch of different religions that were present in the area that he lived to justify everything his culture told him was the correct way to live. Christian Arabs will practice honor killings, because Christianity has not moved the ones that do them away from the cultural belief in them.
If you think Islam is the only thing that "normalizes" honor killing, western born Muslims should be doing them in similar percentages as middle easterners & as far as I know, the numbers are just not there. Instead, you'll find most, if not all cases of honor killing done in western countries being done by people imported from some backward country.
