Selling little bottles of very expensive water with labels that very carefully imply that they do, indeed, cure diseases (while legally not saying anything of the sort) to people who don't know any better is what gets people up in arms.
I've come to the conclusion that victims that falls prey to homeopathy are probably similar to those victims that falls prey to nigerian scams.
When you receive an email from someone claiming to be Prince/Minister/whatever of Nigeria with some large amount of money they need to transfer, suggesting you could be a middle man for a fair share, it is common knowledge that this is scam and fraud. So since Nigeria is so heavily assosiated with this, on the surface it does not make sense for the scammers to continue to claim to be from Nigeria since that would potensially put off more potential victims, right? Well, that is true but it turns out that there is still a benefit for the scammers to continue to claim to be from Nigeria because that also acts like a very good filter to only get responses from those naive persons that will fall victim to the scam.
I think the same goes for homeopathy, Yes, the pyiscs clearly proves that this does not work, but it works nevertheless!. If you are naive enough to fall though that filter, then you are a good victim.
