Saying you're a Christian, but not living like a Christian, doesn't make you a Christian.
Same goes for all other religions. Though IS/ISIS/Hezbollah/Taliban/AlQaidah claim to be participants of the Islam, I can assure you they are not. Because any human who claims to be above God and judge, kill, demolish, terrorize another human being, country or such is not a religious person/group. Its a s simple as that.

It is funny and amazing to read how times have changed.
In the civil war in Ireland, between the protestants and the catholics, never once did I read (as a child) IRA "name of religion" terrorists. They were just called terrorists.
But now since other terrorist groups say to kill and punish in the name of, we call them by their religion.
Shameful.
A terrorist group is just a terrorist group and we should use the name of religion they use to justify their actions to spread more chaos and divided hatred, simply because it's not the religious (christian, catholic, islamic, buddist, hinduist, jewish, atheist) thing to do!

Ya'll need to do some soulsearching, some world traveling and such! Don't buy into the hype the news, the papers, the groups of terror, your government is trying to sell you. Educate yourself and search for the knowledge and truth yourself!

Oh, and before you start calling me names of come out your mouth:
Im the only Christian in my Islamic family and we are all living happily ever after with each other! They've accepted the path that I've chosen and I love being a Christian.
