You may be right about the lack of scientific validity, but r9etb's claim is that the article implies that the US is behind a plot to intentionally blind drug users. It does no such thing.
It claims that the fungus is dangerous, but it comes nowhere near implying what r9etb says it does.
Looks like a poor choice of words, not a carefully crafted essay. Sure, I see your point, but the error of the original article appears to be done with a purpose, not a poorly worded phrase like the other. No offense taken here. God bless.
