Basically all the stuff black people and leftists learn about Reagan. I’m not sure if it’s even still a conspiracy theory but his campaign made a deal with Iran to not free the hostages until after Election Day. They funded Nicaraguan contras by allowing cocaine shipments to inner cities (which led directly to the crack epidemic). Iran-Contra is obviously all accepted history but all the context gets treated as conspiracy theories.

Gary Webb, the journalist that exposed the Reagan Admin - Nicaraguan Contra - crack cocaine thing, is one of those “committed suicide w/ multiple shots” assassinations where the official story is so sketchy, you wonder if they were sending a message to other nosy journalists about what they can get away with.
