Actually, no. Jains simply don't use violence, even in self-defense. It would take quite a literary gymnast to get violence out of commands such as, "Do not injure, abuse, oppress, enslave, insult, torment, torture, or kill any creature or living being."[1] Jain protests can involve fasting[2], but never violence. Other forms of Buddhism (such as Zen) can be violent, but compassion is at the core of Theravāda. This is why there are no Tibetan suicide bombers, despite a brutal occupation by the Chinese government.

Religions really do cause their hosts to have different propensities for violence.

It's too easy to completely dismiss the effects of a particular religion or group. There are uneducated, miserable, humiliated young people from many groups in the world, yet only those from some of those groups kill comic writers.
