It's exactly as Aron Ra says. The Christian position is so weak that they can't be right unless realty itself is wrong. Therefore, they attack reality.
You are being quite silly again.
Where do you think the idea that there is an objective verifiable external reality, that has systematic order, comes from?
It is an idea of the Mediaeval Scholastics, from which Science arose. Fundamentally, the Christian worldview is present within the very foundation of the sciences. It is not councidence that the Scientific Revolution arose in Christendom nor that the Perso-Arab flowering of Sciences came on the back of Aristotleanism.
Those that have been systematically undermining reality as perceived, is Science, not religion. The solidity of objects gave way to atomic theory, whose atoms themselves became vacuous. Consequently with Heisenberg's Uncertainty and Quantum theory, even the determinism and observable nature thereof, fell apart. Macroscopically, Relativity theory dealt a deathblow to objective measurement, as time and length and whatnot, changes constantly. The very fact that observation of an object changes the nature of the observed object, collapses a wave or whichever iteration of this idea you prefer, is significant.
Then in Medicine, Neurology, as I described in the OP, has completely destroyed the idea that what we perceive is accurate. All our observations are altered. Physiologically, we don't perceive what actually our sensory bodies pick-up. It gets even worse when Psychological experiments of our derived observations get taken into account - that we see what we expect mostly, and psychologically can prune out even what should be explicitly observable.
The Sciences has replaced reality that we all supposedly acknowledge, with complex mathematical models and abstract structures. The only thing holding the tenuous silver thread from madness, is the inherited philosophical baggage of Christianity.
When and if this is cut, all bets are off. So long as it remains, then everything loops back, by hook or by crook, if you investigate enough. Idealism, or any claim of verifiable external reality, deals in phantoms that leads the long way home. For there to be data at all, that is anything but pure solipsistic subjectivity, this remains the case. Materialism cannot abide reality as it is conceived, for it has to sneak in assumptions borrowed from religion to remain coherent - if the religious point this out, then the materialist argues the religious are 'attacking reality'.
First take out the beam from your own eye, before looking for the mote in your brother's.
