When you are banging the drum "christian fundamentalism, and islamic fundamentalism, and jewish fundamentalism" you leave out naturalism, existentialism, post-modernism, utopianism like Marxism. All of these have implications for how people live their lives see the world, and ideas about what people need to be saved from. Each suggests some blessings for the adherent. Each suggests a main problem that people need to resolve. Of the lot Christianity simply makes more sense.And?
The OP was about christian fundamentalism, and islamic fundamentalism, and jewish fundamentalism. Not christianity.
Just a reminder. Alas, someone has removed some wrds, to help add confusion to the thread.
When you accuse Christians of being hypocritical you are proving the Christian case. Hypocrisy is an example of a larger issue called sin. That is exactly what Christianity says is man's primary problem. Judging from your argument you would appear to agree with that. The solution Christianity offers is two fold. Forgiveness for the sins that are over and done with which you can't correct, and power to free yourself from future sins.
If by fundamentalism you mean you hold your view on the ground of actual belief, then you need to realize, people ultimately believe what they do. If you really want people to have power to over come sins like hypocrisy perhaps a little fundamentalism is in order.
