I think there's so much drama here because people could have different kinds of candida (candida glabrata va albicans) and when they hear other people touting the same treatment over and over again even though they've tried it and it hadn't worked for them, they get annoyed.
And then there's other people who don't have any form of candidiasis, just a very vague symptom that could be the result of anything. When they feel better, they proceed to call whatever made them feel better the cure for candidiasis.
