You seems to have all the answers...
Not all the answers, just a few, but always meaningful ones.
However, you only gave reasons for the killings from one side that is deem EVIL to you...
I have never given reasons for any murderings. I've just shown how the maniac Jewish sniper is sickly proud of killing children without any reason.
But obviously you felt offended with my post, which suggests that in your view the murderings perpetrated by the Jewish maniac were well justified.
Do you have answers to the killings by the Islamic militants against their own Muslim brothers?
Of course, and very meaningful ones at that.
The first answer is that Islamic militants are so murderous because they too follow the evil teachings of the Jewish butchers known ”prophets” (to which they added their own, Mohammad).
Another complementary answer is that such Islamic State murderous militants are well known to be supported by, and supportive of, Israel, sharing therefore its genocidal ideology.
And a final answer is that you actually don't care about the murderings perpetrated by Muslim terrorists, you probably even sadistically enjoy them, but you use them here as a cover to distract from the mass-murderings perpetrated by Jewish terrorists, which is the topic of the thread.
Do you have justification for killings of Christians' women and children too?
No, but you have. The murdering of Christian women and children by Israeli-supported Muslim terrorists is justified by you as a convenient cover to hide the murdering of innocent Palestinian women and children in Gaza and elsewhere.
Bsidesl, the murdering of Christians (and now of Yazidis) in Iraq and Syria by Islamic State terrorists is a result of their murderous Islamic ideology, which is so murderous because it is an offshot of the even more murderous ideology of Judaism.
Do you agree with these killings by Muslim militants?
Justifying and covering murdering is a Jewish thing, and what you are trying to do right now. I am a Buddhist.
