If I told you I had a friend named Udo, that you couldn't see or hear but I know exists, which you respect that belief? Or would you think I'm crazy?
If I told you Udo is always with me, hears my thoughts, and helps me if I ask him - so long as what I'm asking is in accordance with his will, of course - would you respect that belief? Or would you think I'm crazy?
If I told you that when I die I'm going to take a similar form to Udo - he created me in his image, after all - and the two of us were going to hang out in paradise for eternity, would you respect that belief? Or would you think I'm crazy?
If I convinced enough people that Udo was real and they befriended him, too, and we worked to make society comply with our beliefs - perhaps even killed others in Udo's name because they didn't share our beliefs - would you respect our beliefs? Or would you think we were crazy?
I think we all know the answer to those questions.
And yet, I'm supposed to respect religion?
