Imagine, for the sake of understanding the downvotes you're getting, that your post could be read as "well, science might mostly be right, but we're exercising a lot of caution before relying on the germ theory of disease, because washing our hands could be dangerous; one person we talked to said that, so it might be true, and there are reasons to be skeptical about the quality of soap and the honest of the industry that pushes it". And, not only that, but imagine that comment was posted in the middle of a thread containing many links explaining the problem, and links debunking material that started the anti-soap conspiracy theories.
That post would get downvoted into oblivion, just like yours.
There's a giant pile of anti-science conspiracy theories and "think of the children!" paranoia, started around a single falsified paper, and your comment plays into that. There are already numerous comments in this thread explaining that, including links to articles about the falsified paper.
You're getting downvoted because, in the midst of all that, your posts suggest that your immediate reaction wasn't "we might have some deadly misinformation here that will hurt ourselves and others, we should learn more about this issue, figure out how badly we've been misled, and solve the problem"; instead, your reaction seems to be "eh, changing our minds would be hard, we're 'exercising a lot of caution' instead [and probably won't end up doing anything, because that's how hesitation like that works]".
Changing your mind, really changing your mind, is hard. Finding out that an expert you should have been able to trust was dead wrong is hard. Accepting, as an otherwise educated and intelligent person, that you were wrong about a question of fact is hard. The mind has non-trivial defense mechanisms that make it easy to avoid doing any of those things; people use those defense mechanisms every day, in lieu of feeling uncomfortable or incorporating new information.
