Religions do change. This usually shows in struggles between the progressive and the conservative fractions - that's exactly what you're seeing today with the conservative fundamentalists in the US.
But you are mixing a general statement with a specific example.
I still maintain that these conservative fundamentalists represent a SPLINTER group off of mainstream religion and in now way represent a changing of or evolution of the parent religion.
Jesus is still resurrected after 3 days despite the scientific impossibility of said event... the holy trinity is still alive and kicking in all it's "three as one" paradox... Allah still demands daily prayers... and the Buddha still maintains that suffering is the root of all discontent.
Yes, there have been micro-changes to interpretation, but I believe that the doctrine have been inviolate.
(PS: As I write this, I find myself in an odd reversal of position. Much as I lambast people for incorrectly using theory, models and Facts, so too do I lambast myself for (IMO) not using doctrine, scripture, dogma, and conon correctly. So please correct my usage of these as the posts go on)
