Their motto, Remaing and expanding. The ISIS is known for its well-founded web and social media propaganda, which includes beheading of soldiers, civilians, journalists, non-muslims and especially Jews and Christians.

In my opinion, not everyone has to be under the same religon. People have the right to choose what they believe in. I also feel that these ISIS terrorists should not be so harsh on the non-believers and kill them.
