Based on the first link in post 18, the Copts.
I also ran across some information that in Italy, not sure about other “Christian” countries, up until the 80s a man who killed his wife, sister or daughter for dishonoring the family name received a greatly reduced sentence. IOW, just about the way the same situation is handled today in Jordan.
The law was changed in Italy 25 years ago, but it does go to show that such attitudes aren’t all that far in the past of some “Christian” nations.
It would appear not to be nearly as prevalent as in the Muslim world. And the copts are for the record Egyptian Christians.
Indeed, until 1974, in Texas it was considered "justifiable homicide" in some cases to kill you wife if you caught her in the act of infidelity.
