1. Joe Biden does NOT have dementia.
2. There is no actual evidence that he does
3. The only "evidence" is him stuttering and repeating words in speeches and stuff
4. that is something that happens to literally EVERYONE
5. While he may stutter sometimes and repeat words like a normal human being will do, he has never had be assisted walking down a ramp. Trump did.
However not one of his supporters are saying that he may have dementia,no no no he's a "stable genius"
"In fact, Dr. Jackson did administer the Montreal Cognitive Assessment, a screening tool for dementia, and Trump passed. But while Trump bragged that this proved his superior intelligence, this 10-minute screening test, where one must identify a camel, draw a clock and repeat three numbers backwards, only ruled out full-blown dementia." https://www.usatoday.com/story/opinion/2019/04/09/does-donald-trump-have-dementia-we-need-know-psychologist-column/3404007002/ this is one of several things that hints at it.
Maybe don't go accusing Biden of having dementia when you don't have the qualifications, based solely off of what others who most of them also do not have the qualifications either, while you ignore signs of the same medical condition exhibited by Trump. Now if you don't ignore the chances that Trump has it, then fine accuse Biden of having dementia. There is probably nothing I can say to convince you otherwise but at least consider the chance that something isn't right with Trump either.
