I must be reading and looking at different news sources than everyone else. It seems that every day there are news items about muslim atrocities but hardly any about all the religions mentioned like xtianity, hindu, buddhism etc., etc. Why, only this morning there was a report that some girls captured by extremist would rather commit suicide than be repeatedly raped and used as chattels by ISIS [islamic state] in Iraq. The genocide against Yazidi and other minorities is ongoing. Many of these are children, girls aged 14,15, or even younger that are held as sexual slaves. Amnesty International has claimed [for a change] that this is ethnic cleansing and is also carried on by supporters of the group.
Yes, maybe so. Perhaps, it's as simple as that. News is the telling of stories. Story telling has been the same since ancient times. Never forget that news is entertainment. If it wouldn't be entertaining people would get bored and look at something else. That's especially true for news on TV. It's not a medium that lends itself to in-depth analysis.
We like good guys and bad guys. But there are no obvious bad guys, or obvious good guys in any conflict. It's mostly good against good. We all like to have our preconceptions validated. We like being able to feel that we understand the world. News reporting always caters to these needs in some way. All news is biased in some way. That isn't to say they're lying. There are always a multitude of ways to tell the truth, that will produce different stories. Well... except FOX News. They seem to have no problems with bold faced lying. And then you've got the left-liberal press. Who accurately spot the bias, but then procede to skew the bias too far in the opposite direction, effectively making them as bad as the mainstream media.
In any age each culture has had a bad guy. A character that lazy reporters always can pin all evils on and few people will question it. If you're unsure Just watch Hollywood movies. They'll tell you which are the bad guys at any given time. But we only have one group that is the paramount bad guys. Post 9/11 it was Muslims. Before that Communists (mostly Russian). Before that Nazis. Before that French.
So whatever anybody from that group does it'll be reported, because it validates the consensus. But whenever terrorist acts are carried out by any other group it isn't reported. Because it's not news. It's just a random weird event that doesn't really fit into the big picture. Terrorism has always been a rare event. It's always been so rare that most people might as well just ignore it. They're more likely to die in a thousand other ways before getting killed by an act of terrorism. Islamic terrorism is no different in that regard.
But on your specifics. Any and all wars always have wide spread rape of the conquered population. That's just the reality of war. It always happens. In most armed conflicts that drag on young women are often taken and kept as sex slaves. It's horrible. But it's a fact of war. When "our" boys do it, it isn't reported, or we won't believe it. But we'll get horrified when "they" do it. Also... genocide. The clue is in the name. Genocide is always based on ethnicity. Not on beliefs. If there was some hope that the Yazidis would convert they wouldn't get killed.... of course!!! Religion is irrelevant for genocide. So we can safely say that the genocide of Yazidis isn't about religion at all. You're getting suckered into accepting simplistic explanations for complicated political issues. In any religious conflict, you don't need to dig deep to learn that it's not really about religion. It never is. Never. And the same obviously also applies for the Yazidi genocide. That doesn't make it ok. But please try leaving religion out of your analysis of it.
You just need to look far and wide when you read the news. Read in depth articles from as many and as varied sources as possible. With any luck you will get enough information to stitch together a version of reality that matches as closely as possible to what really happened. It's tiring and often boring. And that's why so few do it, and why news reporting mostly is shallow and dumb.
Nobody really knows what ever happened anywhere. The people on site barely knows. It's not until an event has passed into history that we will be able to look at any news story with sober eyes and evaluate it properly.
