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.
I think people can easily be indoctrinated using Islam. I have also observed that most of their scholar are always enemies of innocent people so the preach hate and ceding of blood as a reward to make heaven. Christian pastor don't preach hate but brainwashing for financial gain to their followers. God help us.
