You completely disregard my argument to Joycey that atheists don't have to supply an alternative theory for their criticism to be valid.
My argument has nothing to do with whether being an atheist or an agnostic is based on faith.
You write, "Everyone has a faith based belief system, even agnostics and atheists."
You're saying that an agnostic has faith that he doesn't know whether god exists. You're saying that he couldn't arrive at that position through evidence and reason? An agnostic needs faith to be an agnostic. That doesn't make any sense.
Let's agree that you have faith that God exists and I don't.
Maybe if you're belief was based on logic and not faith, you wouldn't be so upset when people disagreed with you.
