"Evidence" against Joe Biden: Random photos of Biden interacting in very public settings, re-shared without context.
Cringey? Yes. Actual evidence of pedophilia? No.
It's important to note a couple things:
(1) Biden is a dinosaur. He comes out of an American tradition of old-school politician physicality that used to fall under the heading of "pressing-the-flesh" or (when done with younger fans) "baby-kissing," and now is simply avoided by politicians entirely because of #MeToo (from the Left) and the other hysteria (from the Right) that's been whipped up around this issue. By the way, you can also dig up photos of Trump being handsy with young ones, including his own daughter.
(2) None of these women actually filed charges against Biden: quite unlike Trump, who's been accused of sexual misconduct in multiple court cases. A few said the moment was embarrassing and uncomfortable to them, but none claimed they were assaulted.
