No, for instance, I don't think there's any wisdom or truth to islam, or any that is was appropriated from Judaism and/or Christianity.
And, yes, I got that you aren't a Christian, hence my comment about your not-so-veiled disdain.
Islam teaches giving selflessly to the poor. Is that not wisdom? So obviously, there IS some wisdom and truth...a fact which does not change the brutality and savagery it also condones (for the record, the bible does no less...ordering the death of children in Heshbon, Sodom, Gomorrah and Jericho...not to mention across the globe in a deliberate flood).
As for disdain, I have none for Christianity, nor Islam, nor Judaism. They all point towards the improving of human nature, when read in a reasonable light, but they are all easy tools for those who would misuse their tenets. My disdain is reserved ONLY for the absurd interpretations that are often made by the followers of said religions. Mark Twain was a man who truly understood the nature of religion, and his insight applies to Christianity as it does to all religion. Thomas Jefferson went straight to the cogent point:
"I have sworn upon the altar of God, eternal hostility against every form of tyranny over the mind of man." From the Jefferson Memorial Monument in Washington, DC.
Most people think he was referring to George III. Instead, he was responding to attacks made on him in pamphlets distributed by clergy in Philadelphia during the presidential election of 1800. These pamphlets accused Jefferson of being unfit to become President because he did not hold Christian beliefs.
Twain has one of the best quotes I know of regarding the bible and how it is so easily adapted for misuse:
The Christian Bible is a drug store. Its contents remain the same; but the medical practice changes. None of the above is an attack on Christianity per se, it is simply to assert that it is...like all religion. And as such, it is a ready tool for those who would use it for politics or for personal gain.
