We are humans being, noo angels. And yea there are a lot og "religious people" who are trying to "defend" their religion using words and weapons to harm eachother but I don't consider them as religious, more like some people who overdo it because they're either manipulated by someone else, dumb or they need to because of other circumstances we'll hopefully never have to experience.
I'm religious, a muslim but I'm like:
"If you kill people for your religion, or god, start with yourself" although suicide is forbidden in Islam.
