I gave up watching all of the various “Law & Order” series when they did an episode on honor killings and the perpetrator was a Christian Fundamentalist. 99.999% of the honor killings in the world are done by Muslims, but Dick Wolf decided to go in a different direction.
He must have thought that .001% was unique.
Technically not true, since Druze are big on honor killings. Kurds are among the world leaders, and not all Kurds are Druze. It's not uncommon among various Hindu groups in India. Copts in Egypt are into it, too.
Still, I agree the vast majority are Muslim. Just not the percentage you cite.
