All we need is a bit of jingoism by the "Christian" west and we again descend into xenophobia.
A most recent example is Germany in the late 20s, 30s and 40s which saw the systematic murder of at least 6 million people including Jews, Gypsies, homosexuals and anyone who wasn't aryan or christian enough. Germany, Austria, Italy and France were by and large staunch "Christian" countries.
History is littered with activities either condoned by the church, ignored by the church or feebly protested by the church and carried out by "christian" people to kill, enslave or dispossess others.
The odd mass murder of chinese and aboriginals in Australia was carried out by a supposedly "christian" people. You can be sure that the chinese and aboriginals did not commit suicide.
By all means the world needs to contain the nutters but we need to reach through the smokescreens and call out the baddies and they are generally the mafias who run monarchies, dictatorships and pseudo democracies who enslave their own people and wage war wrapped in the cloak of Islam. Some of those mafias are on our side - so it seems.
