Mate, you obviously know.
But there are some that think it is just a conspiracy theory.
Cloud seeding, yes. (Real, not false conspiracy theory.)
Chemtrails, no. Fuck no. That's Qanon cuckoo-land stuff. Just like DEWs (directed-energy weapons).
Chemtrails for poisoning people or for weather manipulation?
Neither. They aren't "used" for anything. In fact, they (chemtrails) don't even exist: it's just condensed jet exhaust, not chemicals intentionally ejected for [insert dark nefarious purpose here]. Just jet combustion by-products and water vapor.
Look, it's not as if there aren't conspiracies in the world: there clearly are. (Just for one famous example, the Reichstag fire.) But most of this stuff is just horseshit believed by idiots. And that's not you, right?
Oh, these same people believe that forest fires in the US have been caused by "directed energy weapons". They cite as evidence pictures showing a burned car with an unburnt tree standing next to it. Yeah, right: "they" are flying sekrit satellites capable of zapping people's automobiles, presumably because they won't get in line with the One World Agenda or some such shit.
I think we (humanity) are doomed with this level of misbelief ...
