It's not about the religion, it's about the individuals who follow it. If you are a violent person, your Islam, Christianity, Hinduism or even Buddhism, will be violent. If you are a peaceful person, your Islam, Christianity, Hinduism or Buddhism will be peaceful.
It's too bad jainism isn't on this list. They don't even kill insects. In fact, the more extreme ones walk around with brushes and swipe the grass so that they don't step on bugs. The more devout and extreme a jain gets, the less you have to worry about them.
Why is Islam even on this list? ISIS, Al-Qaeda, suicide bombings, 9/11, Paris attacks, Nice attacks, Orlando shooting, Brussels airport attacks, Boko Haram, Hamas, on and on and on. And don't give me the crap that this is not Islam blah blah blah.
