You have provided no such thing. You sent one article, and it's full of shit.
Not only is this garbage written like a fourteen year old libertarian who just discovered Sargon of Akkad videos, it cherrypicks a grand total of seven things out of a list of over five thousand, attempts to randomly assign leftist motivation to them, and still fucks that up too! If you believe this, you'll just as easily believe flat-earthers, creationists, geocentrists and dudes who think wiping your ass turns you gay. The fact that you say the prosecution project is "the only study", as if this has not been monitored for decades, should be fucking embarrassing to you (almost as much as this article pretending the entire thing was just done to cover up Chuckie's death, even though we've known this shit forever).
You want evidence, try looking at how many mass shooters cite these same dipshit podcasters in their manifestos. Check how often random users on this forum show up, talk mad shit and then make weird threats in the name of hating leftists! I know you've been here to see plenty of them. Check any possible source that isn't obviously pushing this same fucking insane narrative. This is page 1 of google shit, and you're here demanding I take this website full of defense for President Epstein seriously. I'm not going to do that.
EDIT: I didn't even notice before but it's blaming the Trump shooting attempts on the left too. Literally just pointing at anything you don't like and going "commulists!".
