From Wikipedia --
QAnon[a] (/ˈkjuː.əˌnɒn/) is an American political conspiracy theory and political movement. It originated in the American far-right political sphere in 2017. QAnon centers on false claims made by an anonymous individual or individuals known as "Q". Those claims have been relayed, developed and supplemented by numerous communities and influencers associated with the movement. The core QAnon theory is that a cabal of Satanic,[1][2][3] cannibalistic sexual abusers of children operating a global child sex trafficking ring conspired against former U.S. President Donald Trump during his term in office.[7]
Trump supporters – many of them QAnon followers – attacked the U.S. Capitol on January 6, 2021. The Capitol attack was a watershed moment for QAnon and led to a further, more sustained social media crackdown on the movement and its claims.[55][56]
Multiple surveys have found that conspiracy theories such as QAnon are most popular among white Americans, especially evangelicals.
