I've been in a discussion with a few people, one of whom claim that it takes "blind faith" to be an atheist (yeah, and he's not even a Christian!).
You non-believers reading this have probably had this accusation hurled at you a dozen times or more. You believers have no doubt used it while you were backed into a corner. For your sake, I'm making this post.
Faith of ANY Kind
It DOES NOT take faith (of any kind) to NOT believe something. Think how ridiculous that sounds: I have faith that Santa isn't real. I have blind faith that there are no leprechauns! Unless you change the meaning of the word, there's absolutely no way FAITH has anything to do with NOT believing a thing.
I can't stand the word anymore...even when other's take it to mean trust. Faith, to me, is not trust. Humanity's ball and chain -- to use Pat Condell's words -- is a plague and people continue to self-infect daily.
I Once Was Blind...
How exactly would one have BLIND faith that, say, there are no homosexual pigeons living inside a watermelon in Sabugal, Portugal? I'm sure that to believe such an absurdity would take "blind faith" -- believing it without a single SHRED of evidence. If we found just one bird living inside of just one fruit anywhere in the world, then I suppose it'd just take "faith" to believe that there are homosexual pigeons living inside a watermelon in Sabugal. But "faith" of any kind to NOT believe it? Get real!
But Now I See...The Light
Think about a light bulb. The light can only be in one of two states: on or off. There's no middle ground there; no "in between". Even if it's dim and barely on...it's still ON and not OFF. That's how belief works. It's a binary state: you either believe something, or you DON'T. (Saying "I don't know" changes the question to one about knowledge...not the same thing as belief.) If you can't say "Yes" to the question "Do you believe...", then you DON'T believe. It's just that simple.
So to believe something without any reason to do so, you need "faith". To believe something in the face of evidence of the contrary, you need "blind faith". But to not believe something because there's insufficient evidence to do so, you don't need faith of any kind.
You just need your head screwed on straight.
