I must say.. that's probably the most flamed argument I've ever had the pleasure (Or displeasure) of reading about evolution. Which had wholly little enough to do with the beginning topic. That said, and my own views upon it muted for the sake of peace...

Yes, I do believe we make perceptions based entirely upon our chosen religion. However, I would ask what you would particularly define as a religion, because based upon my education via a higher faculty (i.e. Collegiate level) it has been described to me as your beliefs in general. That is, our beliefs define our moral code, which thereupon has a direct impact upon our perceptions.

That said, reality has no morals or ethics, with religion aside. Reality simply is as it is, to be interpretted differently by the different denizens of the world. Where respective religions come into play is by offering a prefabricated (for the most part) guideline from which our moral and ethical codes of conduct have been drawn. To say that our upbringing and inherent beliefs (Communal Knowledge if you believe Plato, Observant if you prefer Aristotle) don't influence our perceptions would be entirely dangerous. While I respect Rabbi's faith, I would be hard pressed to say that my upbringing held the same 'truths' that his did.

By saying truth, I'd like to denote that my perception upon reality, is that there are no absolutes. Truths among them, simply because everything is a matter of circumstance, to me. Such a perception, of course, is based upon my belief system that I have built over the course of a relatively short lifetime. So.

The short and the skinny. Do perceptions base themselves soley upon religion? Yes, but the definition of religion would be expanded to include the entire code of beliefs, morals, ethics and other codes of conduct that influence our behavior. Whereupon ultimately, our behavior denotes the perceptions we interpret.
