Careful what you believe in.

When watching this video question pops up in my mind: why is it that many religious people are so spineless when it comes to questioning the morality of what their canon preaches?

In some ways, christianity has a militant structure.  The most important principle is obedience. Not love, not doing unto others, not tolerance -- obedience. In fact,  the ten commandments start off by stating that you are not allowed to even think about following other gods.  (Which is a curious thing to say if you claim to be the only god in existence.  Then again, would you attribute any credibility to some guy with no sense of direction who claims to have spoken to God and would like to share some notes with you?  Perhaps a few thousand years ago)

You do as you are told.  Unquestioningly.  If God orders you to commit such unspeakable crimes as slitting your offspring's throat, you are supposed to comply.  And compliance is hailed as virtuous -- as the right thing to do.  

The inclusion of this story in the christian canon can only mean that a significant number of people (or a number of significant people) think this is illustrative of what being a good christian means.  It is disturbing to ponder that this sort of utter moral perversity is served up in churches with a straight face.  One has to wonder how ministers and priests manage to distance themselves from such vile and base atrocities.

Fortunately, since christianity cannot be trusted to provide a modicum of morality, we have secular values that represent at least a minimum of decency.  The difference between the militant dogmatism of the church and the military itself is that the military does not absolve you from your responsibility.  In the military you are responsible for your own actions and if you have reason to believe that your commanders are in the wrong, you are not only required to not follow orders, but you are obliged to remove your commanders from their duties.  By force if needed.

It is telling that in the secular world, one values morality and decency higher than in the christian world.

It is also telling that the new testament largely seems to be some sort of apology for the hard-line tyranny propagated by the old testament, yet no church of note seems to have seen it as much of a priority to purge the blood-thirsty, petty, unforgiving and morally objectionable god of the old testament from their canon.
