The act of perception is innately subjective. No matter how hard we try to objectify our perceptions, they are still subjective. There is no way to prove that what I perceive as a square is the same concept or even the same concrete object that you perceive. Put it this way. Schroedinger and Heisenberg have philosophically and scientifically argued the objective feasibility of science out of existence.
Human beings are prone to reinterpret the past in terms of their present negotiated reality.
In this way, now that people live in a pseudo-scientific 'milieu,' they are more likely to view religion as invalid. And, religous people are more likely to interpret science as only partially valid. This is all, of course, self defeating, since this perspective is subject to the same problems of objectivity and bias as what it analyzes. So really, all we have to work with is our individual perceptions. I just don't agree that science, just because it lays claim to 'objectivity' and lack of bias, is inherently any more valid as a belief system than religion.
