Beside ISIS, I don't know where you see religious war.
Current or recent religious wars
(they mention some that are 30+ years old, I wouldn't count those but grudges can last long in families/groups)
I do not consider the 2001 war in Afghanistan a religious war. Iraq wasn't at war before the US wanted to detroy some weapon, so it doesn't come from religion.
I agree that Israel/Gaza is a current religious war.
The most horrible wars/mass murder I know about in history aren't religious, WWI, WWII, Stalin/Lenin; Mao Zedong.
War on women.

I'll be your shield powergirl.
But seriously, the war on women in ALL parts of the world is probably the reason we're in such a mess.
In Saudi and Iran they're treated like minors and even worse.
In the west they've been objectified and rendered nothing more than sex objects.
In the east... ugh.. don't want to go into it.
My friend who's half French, half Algerian, told me a very funny story.
Once, he had to renew his ID. His mom along with his sisters (who were all 20+, he was a minor himself) went with him in Algeria to renew said ID. The guy told them he couldn't do so as the mother and sisters had no autority, as they're minors in the eye of justice in Algeria, as they're women. They had to go bother the father to get ***done.
I say funny but, it's just ridiculous to have this in these times and days (because as much as it happened 15 years ago, it's still the same now).
However, as much as I find it revolting how women are treated in this kind of countries, I am just as revolted by the Western princesses we have that have no *** clue and bring Feminism into something beyond, where they want everything and more.
There has to be a middle ground where women are equal to men and aren't seeking to be on top every *** day. SJWs and the example given above are as much of a plague, yet are completely opposites. You'd think our people would learn and keep it in the middle, but no, it's an utopia. We're going toward a huge mess here in the West because of this, the Gamergate scandal is a good example.
