So nothing that you wrote is your actual words.
No because I thought the source would be information enough for you and therefore, I felt that I didn't need to elaborate.
I said that based on a recent survey 91% of honor killings are committed by Muslims.
Ok.
The article appears to deny it:
The article didn't deny it, it merely highlights that honor killings are no more Islamic than the KKK hanging blacks in the name of Christianity. The source clearly indicates that honor killings happen in other parts of the world in different communities that aren't Muslim so we shouldn't view honor killings as something Islamic.
That contradicts all the facts based on actual studies so I asked:
What places is the author of the article talking about?
See here:
It has been found that, in upper Egypt, Coptic families are as likely as Muslims to commit honor killing; Recep Dogan, “Is Honour Killing a ‘Muslim Phenomenon’? Textual Interpretation and Cultural Representations,”
Journal of Muslim Minority Affairs 31, no. 3 (2011): 423-440.
According to another source, it's even found to a lesser extent, in Sikhism:
"Once people with such tribal traditions and psychologies travel to the West, the exacting shame-and-honor codes should no longer apply. But apply they do, at least among Muslims and, to a lesser extent, among Sikhs."

From the same source, the author also acknowledges honor killings among Hindus of the caste system as well.
The article also mentions: "Honor crimes are only part of the larger phenomenon of femicide"
I'm not sure I agree with that. Honor killings is not limited to women, therefore, that statement is wrong since femicide refers to crimes exclusively committed against women.
I take it you didn't read my source because it explains what you're looking for:
"The women and girls who are the victims of such violence are attacked because they are perceived to have violated some profound expectation of how women are supposed to act in their society."
Which means enacting the crime of honor killing is the result of extreme patriarchal customs of a given community which are the gender customs that are perceived to have been violated by women. When it comes to the customs of Africans, Asians, Middle Easterners, there is the perceived idea that honor through the family that is violated must be met with punishment.
