I just noticed and realized that I have never heard of a certain Christian terrorist, all I hear is that when a terrorist is in the news, he/she is a Muslim. I am not saying that Muslims are terrorist, so don't get me wrong.
Because most of the terrorists are those who claim to be Muslims and wrong in interpreting the word Jihad. What they mean by what they have done is jihad, but jihad is not what the terrorists have been doing. Jihad are those who died in the war on defense of Islam, not slaughtering innocent people and shouting the name of Islam. All they do is worsen the name of Islam in the eyes of the world.
