It's not a religion; it's excitement. People who support Bitcoin so fervently just grasp the concept better than you do. If you understood the gravity of the accomplishment and the brilliant potential; you'd be excited about it too.
You don't understand Bitcoin because you don't understand the reason for its invention. You can't grasp an answer for which you don't even understand the question...
Contrary to what you think we believe; We'd rather you not invest in it at all until you can understand why it's important.
Consider: I am pissed that I wasted time on learning about it though I lost no money. You people are pissed because I dare criticize something you claim is valuable. Add that up...
Get it through your fucking head - people aren't interested in shit for its own sake. It has to have value. If people can do fine without something, they will. Most people have no interest in taking on technological skill sets just so some techie can feel useful for finding a longer more convoluted way to do something no one needs.
That's the whole fucking point of product development, and btc currently sucks. There's no ground floor to get in on because it remains riddled with incompetence, perhaps even in concept. So lets discuss that for 20 years on bitcointalk, because that's the visible future of it.
