Honestly I think the thing here is that to you (I'm making an assumption, I don't know this and it's very possible I'm wrong. Just trying to understand where you're coming from and I honestly don't really understand) and to the people close to you the existence of God is just a given fact of life. For most of us God exists always because we are taught about his existence before we can even conceptualize what he is and the extraordinary nature of the claim that he is real.
The stuff about leprechauns and unicorns isn't meant as an insult. We're trying to help you see it from our perspective. For myself God is not a given. I'm a second generation atheist so I have basically never believed. I never "lost faith" or got angry with a church and left, or became overwhelmed with doubt. Being an atheist was never a struggle I went through with difficult consequences associated with deciding I was an atheist. So for me, to be aggressively told that God does exist and that my denial of his existence is a sort of faith in itself, well... I'm taken aback. At that point to me I do ask the question if you have faith that unicorns don't exist or if you take the time to take a position on the billions of things that as far as we know don't exist.
And the thing about that is, I acknowledge that of the billions of things we could imagine but that we have no evidence of that specific thing existing, some of it is going to end up actually existing. There's a whole big Universe out there that we know very little about. But saying that it's possible that some of our wildest ideas will end up being true doesn't make me an agnostic in regard to the possibility of each and every thing that could be. I don't harbor some hidden thought that maybe unicorns do exist and that I shouldn't be so brash and arrogant as to just discount the possibility. I just say to myself, "There is no reason to give the possibility of unicorn's existence any special consideration or to declare that I just don't know for sure if unicorns exist or not." And I go on about my day, not particularly worried that my "faith" that unicorns don't exist will be shattered. To me the existence or non existence of unicorns is a non-issue. There's no evidence that they exist. They don't play a role in my life. To spend an undue amount of time trying to figure unicorns out and searching in my heart to feel if they're real seems pretty silly. I would never do that and no one else would ever implore me to do that. Only because God plays such a large role in you life and the life of those close to you do you see some small tragedy in my lack of faith. And that's what it is, a lack of faith.
I don't take it that way. However you are getting deeper into it than what I am saying. To me faith is the belief in something that cannot be proven. Period. Throw out the religious connotations. Look at God as just a thing for a moment. Can it be proven that He exists or does not exist. No, it cannot. Therefore any stance regarding God, he exists or he doesn't, is a measure of faith.
Faith in something does not have to be al consuming and dictate how we live our lives. For example. The belief around here is that PW is a woman. I cannot prove that so believing that she is or isnt is a measure of faith. I dont think about it, It doesnt dictate anything I do but since I cannot prove it and stance I have is a measure of faith.
I am only using God as an example becuase He is the easiest example. I am talking about a literal definition here. A belief, one way or the other, on something that you cannot prove is faith.
