I think what you say would make sense whether or not Chomsky agrees and whether or not Trump is acting guilty or scared or just playing with your mind for the fun of it. But you need to explore why some Democrats cannot look at this rationally, cannot weigh the costs and benefits, and cannot step back to ask why they must fight to the end to achieve a non-electoral overturn of the election. Beating Trump in the next election still means he won the last one. If he won, that means they were beaten by him. That means a large number of people detested them so deeply they voted for Trump instead. The thought is unbearable. There has to be some secret conspiracy underneath it all that rigged the election for Trump. There has just got to be. They could not have lost to him, definitely not to him.
So you made a sane argument. But will it convince the fixated Democrats? I doubt it.
