Well I'm a scientist, and as far as I know, homeopathy works for me.
I don't know know it works, but it does. I also know a lot of other people scientists and reasonable rational people for who it works too. Some of them also take medicines made by pharmaceutical companies, to varying effect.
As far as I'm concerned we haven't looked at it properly. Make of that what you will fellow scientists 
I guess it's ok to have an opinion about religion, but as a scientist I can't say how some people seem to get relief/ comfort / cures from that either. And yet they do.
Perhaps we should store up our unsubstantiated opinions for a MN desensitisation inoculation or something!
But seriously, it's not a very productive discussion if we are all banging on about our opinions on something being crap despite others saying they have had benefit from it now is it?
