Is it?
I can support that argument. The (all?) is clearly a question. Practicing a religion "as it is written" is what lead to the Crusades, the prosecution of Gallileo, the horrors of the corrupt early Popes, the slaughter of the native peoples of North America, most - if not all - of the thousands of years of violence in the ME, The Spanish Inquisition, etc. ad plenty-o-nauseum.
And I think it is unsupported - I believe that most of these horrors were done for secular reasons, and justified by religious argument. I believe that most historians wou;ld back me up, as well. Gallileo threatened the secular power of the Papacy, for instance - the corrupt popes were, well corrupt - and used the church as a vehicle for wealth and domination, most of the native peoples of North America died of disease, the rest had thier land and posessions stolen - saving thier souls was only an excuse, just some examples.
Look - NEVER in this thread have I even implied that the various religious texts weren't used as an excuse for abomination; I simply believe that people can twist ANYTHING in order to rationalize thier own behaviour. I amn not immune (or superior *grin*) to this, you are not, atheists are not, muslims are not, followers of the Tao are not.
I believe that both the desire to avoid personal responsibility and rationalization are both at the root of human evil.
Not religion - especially not a particular type of religion.
Not even general ideology.
The flaw is in all of us.
