That CNN headline would be very misleading, because most people assume that Egypt is 100% Islamic, not knowing that 10% are (still) Christian. Hence unless they specifically state "Christian worshippers", CNN probably deliberately ignores the fact that it is Muslims killing Christians, as it has been since the 600s, and gives the impression it is poor innocent Muslims being killed.
Another fact they prefer not to deal with is that the Muslims are undertaking a new "final solution" by oppression and expulsion of all remaining Christians, just like they expelled or killed all remaining Jewish people in those countries in the late 1940's (AFTER Islamic-allied Nazi Germany did the same).
It is absolutely guarenteed that there WILL continue to be a civilizational war between the Muslims and the rest of the world, over the next several thousand years. But if our own media outlets mislead us by pretending it isn't happening, or that it is somehow our own fault, that just emboldens the Islamists.
