Whenever my boundless pessimism and skepticism regarding spirituality comes up as I'm talking with my friends, I am always berated with the knowitall phrase 'there is more between heaven and earth', and the smug bastards all fall over each other priding themselves on being more open minded than me.
It's not like it takes any effort to believe in Santa, Jesus, Asmodeus or the tooth fairy, and they never qualify why it's better to jump to conclusions you can't support.
