You can't believe in something without having a reason, so I feel that faith still has evidence behind it. It's just that the evidence that is needed for someone to believe in something varies from person to person. Someone may believe in an idea because of the feeling they have from that belief, others because they see the effect of that belief on the people around them, others because the people they love and trust believe in the same idea, and others because they view the evidence around them and feel that it suggests that idea to be true. I don't really think such a thing as "blind faith" exists. People who are accused of blindly believing in something still have reasons to believe that particular idea, it may just not be the same quality or kind of evidence that is required for other people to believe in those things.
Personally I wish that people would have a higher standard for evidence, and wish they'd analyze the evidence they see without letting their emotions get in the way. I think that beliefs developed through logic rather than emotions are better, but quite a lot of religions promote having emotional attachments in the ideas, that's why they can be so hard to shed. It's hard to convince people to think differently though, that's why I hope to teach my kids some day "how" to think, not "what" to think. Let them come to their own conclusions.
