Marvel set a precedent when they called attention to the Sayf "Jewish" thing and got headlines for addressing the issue and correcting it. They don't get to pick and choose which religions get offended and which ones don't find offense. They opened the door and shouldn't have repeated it. Of all the other things Natesus could have eliminated from the world this one was always going to be controversial.
It's just a shame they aren't taking it seriously.
