I entertain few beliefs, but no, i don't necessarily view things though the lens of my beliefs, nor do i have any good reason to assume that "everyone" does. In fact, the virtue of tolerance comes from being able to see things as other people do, whether or not their beliefs are consonant with one's own. This is one of the prime reasons that people become disgusted with organized religion, or mere religious beliefs, even if not associated with an organized religion--that those who hold certain beliefs are unable to step aside from those beliefs and see the world and the other people in it in as objective a manner as possible.
I also disagree that our beliefs are formed by how we perceive the world. Rather, how we perceive the world will be conditioned by our beliefs, unless we make an effort to overcome that limitation. You are contradicting yourself. You are defending seeing the world through the lens of your belief, and at the same time you are attempting to claim that you started this thead so see how others think about Christmas. If you truly wish to do that, you're going to need to be able to discard the prejudices which your beliefs impose on you.
