"What makes you think that religious people are not happy?"
Because of all the people I've met, the free thinkers are, without exception, happier (and more interesting) than the religious people. Also, because at one time (as a child) I was open to the idea of God, and ever since I gave up on the idea of mystical, magical mythology as being true I myself have been much happier.
There are some parts of religion that I would love to see replicated in secular society; the strength of community, regular (weekly) meetings, and unity. But the parts of religion that offend me are the most ancient, darkest parts of our humanity. To see what I'm talking about, read the bible quotes at:

"Happiness" means neither promiscuous sex nor drug addiction. This seems to be a common misperception conservatives have about liberals.
Do not confuse "happiness" with "instant gratification". I'm talking about the important things in life.
"Maybe we should just give it all up, go on welfare and spend our days soaking up the FUN! Party at my section eight housing residence!! Whoo Hoo! "
If the world really worked that way, I'd be all for it. :)
