Re: Not covering head and face with hijab and niqab and dating
I'd doubt the Ulema are the ones that tell the fathers to kill their daughters for not wearing hijab. And if such is the case, then they need to learn proper Islam too.
Actually by educating them about Islam, you are not blaming it on Islam but rather teaching them what you wrote in your first part. Even the Quran says that you that if you kill 1 soul unjustly, it is as if you killed humanity and if you save 1, it is as if you saved humanity. So yes, this does play a role.
Of course, when you murder someone, you believe that you're in the right. Hence, he believed he killed her justly, at least when the action occurred.
The problem is perception. Religion does not save us from these problems, because everyone's perception differs, no matter how clear cut you view things.
Morals are not given by religion, they are merely warped or reinforced by religion. As a species, we must respect each other, and never dehumanize others, regardless of our differences. Religion does not save us from such ills, in fact, they often make them worse.
The often common factor in many of these tragedies is that the victim is female, and the perpetrator is supposedly Muslim.
We need to look at why patterns are repeated so often.
