I have a quote on my desk at work...and I am paraphrasing here because I can't off the top of my head remember exactly... Let us focus on helping others in their time of need rather than imposing on them what we think they should believe.
I agree 100% with sewsplendidstamper, it's the people for the most part that wreck the whole thing. The self rightous ones who think that they have it all down are the ones who are the furthest from the truth. I don't have a problem with people who subscribe to religion; it's the arrogance of thinking they are the only ones have it right that bothers me the most.
Ask yourself, "When Iím on my deathbed, will I be glad I was so serious about _______?" Let down your hair and stop being so darn important for a while.
