How do I know? Because we live in a freaking society. People over 65 aint fucking aliens. They don't live under a rock. They leave their homes. They have lives. In other words I have been coming in contact with people of Biden's demo for over 36 freaking years. His behavior is nothing close to typical behavior for someone his age. There is a reason John Stewart had a segment hosted by Samantha B called the "Audacity of Grope" featuring Joe Biden and no other government officials in his age group (not saying there are not a shit ton of gropers in the House and Senate, just saying they don't have the audacity to do it in front cameras). I grew up in Mississippi, my dad's fam is from New Jersey, my mom's fam is from Missouri. In none of those states has anyone 65 or oldder, or 65 and younger ever put a hand on my face let alone two and kiss me on the head, like Joe Biden likes to do with other people's children, nor have I ever seen anybody do that to children who are not in their family. And buddy let me tell you I spent half my summer at light house point yacht club in Tom's River New Jersey, the vast majority of the people there were north of 55 and not to mention tipsy the majority of the time. No old man ever put his hands on me, I never once saw anybody sniffing anyone's hair. To this day I have never see anyone sniffing anyone's hair who wasn't their SO, and I still haven't seen anyone put both their hands on a child's face who they are not related to face and kiss them. It's not normal behavior.
On to the predator claim. There is countless video documentation of that slimy shitbird making people uncomfortable, so uncomfortable they throw a get the fuck away from me look followed by them moving away, what's Joe do? He goes in harder. He's clearly not doing this because he's "just a kind old touchy feely guy" otherwise when they show disgust he'd back off like any normal person from any demographic, he's doing because he can, he's doing because he doesn't give a fuck, he's doing it because he knows he will suffer no consequences, because he has clout.
