There's so many these days. The Democratic party is a child sex ring operating out of pizza parlors, "globalists", vaccines causing autism, Obama was born in Kenya and is secretly Muslim. The dumbest has to be "the great replacement" which is a racist trope on the internet, apparently Jews are making non-whites outbreed and eventually outnumber Caucasians because minorities are unquestionably subservient to their whims and wishes.

I've heard such wild conspiracy theories I don't know which is most wild, I probably don't even remember most of them. Two that come to mind are (1) Birds aren't real, the government killed them all and replaced them with surveillance drones, and (2) The moon is a hologram. Oh and Flat Earth would necessarily have to involve a lot of conspiracy too. The conspiracy theory 'd me most inclined to believe would be that 9/11 was an inside job, or that JFK was killed by the CIA.

You heard of so called Chem-Trails ? Very wild. But I'm inclined to believe that there are Elves and church still hunts them down.
