Brooo. You got it completely wrong. My post has got nothing to do with the yazidis. Genocide against Yazidis is completely utterly wrong but the incident that I was talking about in my post happened 1400 years ago. The guy who did it was named Yazid.
As a Muslim, this is my responsibility to tell you that whatever a person of other religion is doing is 100% their right to do. No one can excercise violence on them. The most important example is that of ISIS. They give themselves a Muslim identity but what they're doing is totally forbidden "Haram" in Islam.
