Also, this...

Does Christian Fundamentalist extremism pose an equal threat? Not yet, anyway. In most Western democracies there is a long standing tradition of separation of church and state, even though being put under seige by the current crop of neocon knuckleheads.

The Christian religion does not have any "long standing tradition of separation of church and state". Some western democracies have such a tradition, but those democracies include Muslims along with the Christians, Jews, Buddhists, Hindus, Pagans, etc. that make up their populations.

Conversely, we have seen that Christianity, when married to totalitarian political systems, is just brutal and repressive as Islam is now, or ever has been. The main difference is that there presently aren't any countries with totalitarian political systems married to Christianity. So the problem, again, is not the Muslim religion... it is totalitarianism married to religion.

There are and have been countries with democratic political systems and Muslim majorities, in which there is a separation between the majority religion and the government.
