I would think that inferring something untoward happened going by such a remark, says way more about that person than Sleepy Joe.
Well I think that the media on all sides, constantly does this. They constantly look at phrases, or behaviors, and infer absolute villainy wherever they can. My concern is that the fact of this practice, of social neuroses on the media level, might actually inject real suspicion and anxiety into the general social construction of society, goading on / or generating bad behavior just by planting the seeds for it
That said, I myself do sometimes get a creepy vibe from biden. I also think trump is fairly creepy. But a mere recollection of how old he was, and how old someone else was, without reference to misconduct, really should not trigger an automatic inference of villainy in a normal mind.
I think that the white collar, upper culture people who work in media must constantly do this - constantly see everything in terms of pretense. And in extension, I bet that everyone in the upper class does this, maybe they all see their reality at the top as being built on pretense. Which actually says something disturbing about our upper class culture, and might make me glad to be blue collar, where people can at least be a little more down to earth, and not have to read into each other quite as much. That is to say, it is far more obvious if a blue collar individual is acting badly, or is a jerk
Though at the same time, media and upper class culture tries to train us all to think in terms of pretense
