I think the disinfo people like to throw out the arguments of "no proof" and then disappear just to get the people who are reading, but skeptical to back off and say to themselves, "you're being silly, there is no proof", but if they would continue to read, and watch the videos that share the government documents that approved chemical spraying of biological agents, then they might rethink their positions.
