Nah. You have stuff to read right in front of you, and it's easily verifiable. If he says something that's wrong, or you don't agree with what he said, say so. But don't ignore what he wrote up and just say he's wrong cause he's been wrong before. That's poor.
You can google any amount of pretty much any speech Pres Biden has given since he became president, and it's very, very obvious the man is having cognitive issues, whether it be just senility or alzheimers or dementia or something else. It's well beyond "stumbling through a sentence or two" or any sort of thing you can attribute to any previous President.
And it doesn't matter *at all* if Crunch was just as critical about Trump, or Obama, or anyone else. Pres Biden's mental state has exactly zero to do with Crunch's political leanings, or bias's.
"If Trumps communication idiosyncrasy's didn't bother Crunch Biden's should either. " - bad logic, bad arguing.
"But Crunch has been pushing the dementia angle hard, and by now everyone probably just automatically pushes back against him. This goes back to that credibility issue mentioned earlier." - maybe he's been right all along. Stop automatically pushing back and read what's at hand.
"Glad to see you finally got around to reading Nineteen Eighty-Four, since you obviously hadn't read the book during the Trump years." - bad arguing. Google logical fallacy's please.
"He selectively quoted the man.
Crunch gave us a bunch of sound bites without attribution." - attribution to what? Context isn't important when pointing to the man's potential cognitive problems. Unless he made up the quotes which would be easily verifiable, the proof is right there in the pudding. President Biden struggles to put together a full sentence or a coherent sentence. And it's not like this is out of thin air; President Biden's mental health has been something of a question for some time, and not just by Crunch.
