Alex Jones didn't just say there are chemicals in the water turning the frogs gay. Alex Jones said the government was deliberately putting chemicals into the water as part of a chemical warfare operation to increase the homosexual population and reduce birthrates, and that the frogs turning gay was the proof.
It doesn't matter that he was a little bit wrong about the actual effect of the chemicals on amphibian sexuality, he was very wrong about his actual claim, that being that gay people are bioweapons in a secret program of mass human genocide.
While Alex Jones was undoubtedly wrong on that one, I believe the source of his misinformation didn't come out of nowhere. Which is exactly what the parent comment was trying to illustrate. Take a few pieces of truth, fill the gaps with wild imagination and emotionally charged responses, and you get Alex Jones and his content.
Back in the 90s, US Air Force Research Laboratory was indeed working on a halitosis bomb that would do exactly that - turn those impacted by it gay.[0] As far as the wikipedia page goes, it seems like they didn't succeed in producing an actual halitosis bomb (and I have zero reason to believe otherwise, but I bet some Alex Jones supporters might disagree with me here), however it was included on their 3 pages long proposal paper for possible nonlethal chemical weapons. Which proves that there was some research on it and that the intended purpose of the hypothetical "gay bomb" was to use it as a nonlethal chemical weapon.
