Don't be sad. Biden's been a liar, plagiarist, and crook his whole political career, and he's still walking free despite his crimes. I'd abuse him even more if it was up to me.
You left out pedophile. I clicked on the link and it was sad to read all the comments from people defending him.
Yes, he's all those things.
It's a quirk of my personality, I supposed, that I can look past all that and see that he is being abused by those who should be caring for him. He clearly has dementia and is probably mentally ill (unless sudden screaming fits are part of dementia... I don't know.)
It's the situation that's sad.
