They were not referencing some random physical attribute. Trump’s supposedly tiny hands is literally a funny meme - https://knowyourmeme.com/memes/donald-trumps-small-hands

You’re on the internet. Where everything is mocked by faceless trolls on every side of the equation. People who mock Biden for his age seem to forget that Trump is only three years younger. Not exactly a young spry chicken either lol. Still that doesn’t make the jokes any less funny when people laugh at either old cuck for stumbling. Just retire grandpa - let the next generation take over for Christ’s sake.

Learn to lighten up and laugh. To quote Elbert Hubbard “Do not take life too seriously - you will never get out of it alive”
