I'm afraid to say that I don't think that's even surprising, even people you would presume to be more sensible than her (a certain few HN commenters for example) continue to spew this nonsense. If you think about it, these are people who have been deep in conspiracy theory territory for quite some time, and have invested a good deal of mental effort into eradicating any doubt in their own minds. They have preformed enough mental gymnastics that in their minds, any proof presented against their delusion is actually proof in support of it. Accusations of fraud only strengthen their resolve.
Anyone how has objectively been following this issue for the past few years should have caught on quite some time ago, why should they only wisen up now?
