That Obama was Muslim? Well, I heard from people being serious that he was the Anti-Christ, as a popular opinion on Sodahead back around 2008.
Everything I’ve heard the QAnon people say is way up near the top of the most wacko stuff:
(Trump is a hero secretly trying to save us all from the pizzeria-pedophiles Hillary and Obama and the military space lasers that California has been using to set the wildfires in order to get Federal relief money which fortunately Trump realized was a scam and so wouldn’t give them, which you can tell because the fires burned some houses to the ground while sparing others which is obviously space lasers, and Trump created the Space Force to reveal that we actually already have a space fleet which we haven’t seen yet because it is hiding behind the moon, but is great because there is a space alien fleet that plans to threaten Earth, and it really starts to make sense when you hear about the Nazis who, when Germany was losing the Second World War, fled in force successfully to the Arctic ice caps, but was pursued by the USA and the result was Nazis coming to the USA… etc…”)
