It usually does just go away. I lived on an off in the Middle East from 1983 to 2011. Taught in their schools to. This type of hyper Islam comes up on a regular basis as people try to out pious each other. It goes in cycles while people just try avoid being caught up in it. So there are always whirlwinds of Islam going about but the societies spend a great deal of time putting out such statements while everyone does their best to ignore them,

You see the same thing in the USA with statements from the religious nutters on this and that and yet another end of the world...
