On can choose to "believe" anything one wants, but one cannot make a claim to truth. It's when truth is claimed that problems arise.For example, even with Jesus holding forth in defense of the poor and the persecuted, the Bible basically condones slavery, the righteousness of slavery.. Slaveholders were on the winning side of a theological argument and they knew it and they made a hell of a lot of noise about it. Slavery was abolished despite the moral inadequacy of the Bible, not because of it's treatise on morality.
Someone once said that "Faith is nothing more than the license that religious people give one another to believe such propositions when reasons fail." As BB has said, it is the willingness of science to say "I don't know"- to really integrate doubt into their view of the world, to test all theories - that constitutes their privileged position with respect to truth. There are an uncountable number of questions upon which religion once offeredfaith-based answers (no doubt chosen with the comfort in mind of those giving the answer), which have now been ceded to the care of science. We hardly need examples, and there are many we can cite in this day and age. Was it Dawkins who wrote that"the process of scientific conquest and religious forfeiture is relentless, unidirectional, and highly predictable"? What is also evident is that thoughout the ages and evenin some cultures today, there has been/is an eagerness to subjugate and even murderthose whochallenge "the truths", thedoctrine, to which the religioushave become emotionally attached.
