The way I see it Trump lied and Biden lies / lied too. One isn't worse than the other in that respect, but I will say Biden's worse as a delusional serial liar. One of his worst aspects is when he's called out on it he becomes incredibly insulting and angry towards the person that called him out, particularly if that person is perceived by him to be 'beneath him' in social status.
Biden sees absolutely nothing wrong with berating some working stiff or small business owner who calls him out for a lie, or because their own political ideas don't mesh.
As for your post, it's one big set of complex question fallacies.
