consider that the ideology of martyrdom, has both a Christian face and a Muslim face.
There are a lot of Muslims saying they are being misrepresented and Islam is a religion of peace. On the other hand, Christians are claiming Islam is a religion of violence and Christianity is about love and peace. The fact is, if you take their respective holy books at face value, both religions promote bigotry and violence.
Modern Christianity and modern Islam both promote peace, but that is because ignore their own texts in order to bring their religious belief systems up to date with our more enlightened times.
The root of the problem is that faith - belief in the unproven - results in vunerable people being easy to convince that the evils they do are actually holy and a requirement of God.
