That's not possible. Faith is believing in things that you know damn well aren't true.
Atheists beliefs are supported by the evidence.
BULLSHIT!: I do not know what the original grievance is between you and Loupgarou, and it doesn't matter for this post. You simply said some things that I disagree with.
When you say "atheist beliefs", I will assume that you are referring to scientific beliefs. (If by "atheism" you mean "positive atheism", you should know that there is an equal amount of rational evidence for and against the existence of God.)
The scientific method does not exist in a vacuum. All scientific principles and experiments are ultimately based on a set of axioms that science basically takes on faith. Without a few basic assumptions, science does not work. For example, it must be assumed that the world is measurable, that the scientist in question is not hallucinating all of existence, that a supernatural entity is not manipulating the results of experiments, etc. You may believe that these are "absurdities", in which case I invite you to prove them false. Your prejudices about what "makes sense" are irrelevant to science. There are many scientific discoveries that do not follow common sense but are nonetheless true. Who is to say that the axioms I mentioned are not also true, even though they defy common sense?
Mathematicians is infamous for engaging in this sort of faith-based behavior. There was a logician named Kurt Gödel who proved that there is the possibility that mathematics is self-contradicting. If an inconsistency like this is ever discovered, the certainty of every mathematical theorem in history would (probably) be torn to shreds. There is no guarantee that it will not happen. In effect, mathematicians everywhere are engaging in a giant act of faith by staking their work on the belief that this will never happen.
We all choose the axioms that we use to make sense of the world. If someone decides to choose as an axiom "God exists", you have no business criticizing this decision unless you can rationally prove that the axiom is incorrect. Your implication that faith is inherently wrong is misguided and does not do justice to a logical philosophy. What a person chooses to accept on the basis of faith alone, in an area where only faith can provide answers, is that person's decision. You should not dismiss faith so lightly.
