uhm those are definally wrong translates of koran.
there is no kill them or something on it :l
send me the translated parts in arabic and i'll give you the right thing
oh and i just remembered something
did islam declared world war 1 and 2 ?
no it didn't germany,usa and others did
did islam made hiroshima bomb and killed millions of people
no it didn't
usa did
so pls look at the close things to you before looking to the far things coz it may hit you in your way

This is a bit beside the point.

You have your interpretation of the Islamic text and so does ISIS. You may not like their interpretation and disagree with it but it's an interpretation nonetheless.

Thank you for the offer, mind if I take you up on it?
