As a non Christian, I think a lot of the times we ask where the proof is because we would like to have faith but have a hard time believing in something that is not backed up by scientific fact. That said, a lot of ppl with a faith believe in it because of their own personal reasons that just cannot be proven in a conventional way. I don't believe anyone believes anything because it is forced on them by other religious ppl. Those who grow up within strict religious families often stop practicing the religion of their parents. We make up our own minds and live how we choose.

I think a lot of Christians speak out so much about their faith because they are honestly content with life and just want to share it. They just want to help others that seem lost. The trouble starts with ppl who twist Christianity around and try to force their judgement or corrupt ways, they get the most publicity and ppl start thinking all Christians are crazy, right-wing wackos.

Ask yourself what you believe in and what you have faith in. Then ask yourself why. My answers to those questions can't be explained or proven, and may even seem silly to some ppl but they are what I believe in and I think that most ppl can respect that. I don't think anyone who asks for proof does it with malicious intent.
