Why are Muslim people killing Christians?

[soso surprise]

Boko Haram O.o weird name
forbidden Boko O.O
why don't you blame Jews for whats happening in Palestine. do NOT give me the whole "they are defending them selves and they are God's chosen people" crap
how about why don't you blame Christians for what Hitler did. why don't you say "Christians were killing them selves in WW1 and WW2 and WW1 had really no reason"
why does no one say anything about how (again) Christians dropping two nukes on Japan and their excuse would be "it was the only way to stop WW2" thats the worst reason EVER!!
how about why don't you blame AGAIN Christians for its invasions such as the British invasion and the French invasions
(whoa so much things that Christians did and YET they are called peaceful people"
so think twice before you blame Muslims.

@ROBERT P: Arabs are also Christians and Jews. just saying and your "answer" sounds like a fairy tail to me.
