If you're looking for a website like QAnon, but catering to gun control advocates, you will enjoy some articles from The Trace, a gun control website founded and funded by Michael Bloomberg.
In August, The Trace presented a conspiracy about the amicus briefs filed in New York State Rifle & Pistol Association v. Bruen. The article was reprinted by Politico. Will Van Sant, The NRA's Shadowy Supreme Court Lobbying Campaign, Politico, Aug. 5, 2022.
The Politico reprint of the Trace article opens with snazzy graphics. Forty-nine amicus brief were submitted in the Bruen case: "12 of those briefs were filed by people or institutions who had received millions of dollars from the NRA, a Trace and Politico Magazine investigation found. Only 1 brief disclosed the financial connection."
