Anything that encourages debate about important things in life to some people have a purpose.
I imagine that the tooth fairy is not that important to most people so the non-belief in it isn't either.
Well I'm sure homeopathy is beneficial to some, religion I believe has a purpose as does atheism, self mutilation not so sure :)
It's just the bigotry on here that sets me off. Got to stop coming on here as I suppose I'm displaying it now.
I'm sure the millions of people who use acupuncture around the world will now dismiss their personal experience and stop as the almighty Voroshilov has spoken.
